OP Classes in the Mass Effect series.

I agree on ME1, with a few notes. There is little reason to include Soldier without also adding in Infiltrator. There is very little difference between the two's damage and defense in practice. On paper, the Infiltrator does take 40-50% more damage (depending on mods), but in practice they are both invincible. Master Immunity is very broken, you often end up regening faster than you take damage. As for Adept, I'd rank it third, and mostly for Bastion. Early game Adrenaline is nice, but late game a Bastion's Lift has an 8 and a half second cooldown, and lasts 17 seconds.

For ME2, I'd agree on Soldier being number 2, but it's not even in the same ballpark as Assault Armor Sentinel when it comes to being overpowered.

For ME3, I'd probably say the Infiltrator. They have enough slowdown between talents and mods to shoot rockets out of the air as they are launched for a nice AoE. Add in the cloak cooldown change, and weight isn't really an issue with them. The only thing slowing them down is lack of bleedthrough on Insanity. If not them than probably the Adept because Biotic Explosions are very nice. Or the Vanguard, just because the Biotic Pinball is all you need for most things. Hell, they have a move that takes away your shields but actually increases survivability, and does a boatload of damage. Really, any imported ME3 character seems to be pretty nuts.

Is it really possible to maintain a constant Marksman?

Only as a Commando, with the Pistol Achievement and 2 Medical Exos.

But you have to remember that the Infiltrator doesn't get useful passives like the Soldier. But he does get Damping, which is not bad.

And Overload. It might be half the strength of Warp's -DR (since most builds won't take Warp to Master), but when facing Immunity spam, it's a hell of a lot better than nothing. And yeah, Soldier can take Warp, but they give up Lift for it, which is a hard call, plus with no bioamps or much cooldown at all, their Warp is going to be taking a lot longer than an Infiltrator's Overload with a nice Omnitool, and the fact that you are using 2 MediExo's anyway for Immunity/Marksman spam, that Overload will be popping up pretty quick.

Please explain the Sentinel.

Assault Armor Sentinel can't die. For one thing, the "back up shielding" when Assault Armor breaks actually does factor in shield bonuses, unlike Charge, or most other abilities which only work off of base shield.

But the main thing is shield breaks. You are immune for a little bit when your shield breaks in ME2 (they drastically lowered the duration of this in ME3). So. Assault Armor break, immune, backup shielding breaks, immune, (possible) redundancy generator breaks, immune. Refresh Assault armor. And some of those shield breaks are doing the massive Tech armor shockwave. It's pretty similar to how you can chain the immunities of Charge and Nova in ME3.

The guy makes a small mistake in reactivating Assault Armor late, but it doesn't really matter. Assault Armor Sentinels can do what a Vanguard does, better and safer, without needing a target so no "can't get a lock", and they have the option of have all the perks of "no cover, reshielding" while staying at mid range with an AR if they want.

That being said, I don't see whats OP about them.

Scaling cloak recharge means weight is pointless to them if you play smart. And in Singleplayer, with their passive and a concentration mod, they can basically pause the game to line up shots, not usually a huge deal, but it makes the Black Widow incredibly silly.

And above all, I can't believe you fail to even put Engineer up on that list.

I haven't actually played an Engineer in ME3 yet. My ME3 part was mainly just saying "Everyone I've played in ME3 is overpowered so far, except Soldier. But I'd probably give Infiltrator the crown".

And the Adept may have more combos to use for the Biotic Explosion, increasing their usefulness. However, most of these triggers require the protections to be off. They are not as OP as the Engineer.

Warp->Throw gives a +100% explosion (they both have a bonus), and can only be stopped by a barrier. (Warp bypasses all defenses for "arming" the combo, but a Barrier stops Throw from detonating) That's why I like an Adept with an AR+Warp Ammo.

Engineer is without a shred of doubt, the most OP in ME3.

I'll have to try it some time. I just find the drone so boring. Well, I find Tech Armor boring, but I don't really play Sentinel the "right way". I go Power Armor/Guardian, and see how high I can launch ice statues. They are the only class that's really set up to do this, and I still have no idea why Cryo messes with Throw's physics so much. Sometimes they barely move, other times I get Krogan stuck in rafters, or one of my favorites, was launching a LOKI over the warehouse ceiling lights on Garrus's Loyalty. Or ramping one off of a box in Miranda's Loyalty and it slid along the ceiling at Mach 5. That the was time that proved to me that allies are super accurate, Miranda was tagging him the whole time, with the Tempest.

But anyway, other than that aside I have a hard time getting myself to play Sentinel or Engineer in any of the 3 games.

all the perks of "no cover, reshielding"

Wanted to clarify on this, since "no cover" by itself doesn't sound like much of a perk. In ME2, if you can get through a battlefield quickly, often you can keep extra waves of enemies from spawning. It's one of the things I like about playing a Vanguard, you are playing very risky, but often you can end a fight much earlier just by getting to the right spot.

Assault Armor Sentinel can do the same thing, only without the risk. Going all upclose and meleeing and everything has nowhere near the risk of a Vanguard doing it, and they still have the option of playing it even safer by pushing forward while staying midrange, and still getting a similar result.

However, I noticed that he came close to dying several times.

He only really came close once, and his Tech Armor was already cooled down before his shield even broke, he just wasn't using it for some reason. Maybe he likes the veins =p.

This kind of style cannot be applied to all battles. If the battle was a little more intense, I doubt he could pull that off.

I've always found Horizon the hardest mission. The game gets easier as you level for the most part. I haven't beaten the game with my Assault Armor Sentinel, but those who have seem to agree that it's godmode. As for why I haven't beaten it, I find it really boring. It really is a better Vanguard, but the risk is a lot of what makes the Vanguard so much fun.

I don't consider the Vanguard OP

I died on my first Vanguard more than other playthrough, so I'd agree. A lot of those deaths are from it being pretty hard to dodge a singularity at point-blank. This hurts me.

The performance displayed was due to the player's skill, not the class' basic abilities.

I find the most useful thing to learn as a Vanguard is to use Line of Sight to your advantage. Pillars are god's gifts to Vanguards, since half a second of their bullets hitting metal instead of you is half a second closer to another charge. In other words, it's all about the foot work =p. Same with Scions, hold down shotgun trigger, get close then back away, it'll use it's burst and miss, keep repeating. If there are 2, Charge whenever you hear the other guy Shockwave while doing this. I usually think that if I'm cowering in cover as a Vanguard, I messed up. Or there is a Pyro in a bad spot.

When I talk about OP, that class has to have basic advantages and much higher performance.

Well, then why list Adept for ME1? Its DPS is only decent with an AR, and it most likely won't put more than 7 points in that AR. Its defense is average at best, since Barrier is absolutely terrible next to Immunity and a lot of things bypass shields in ME1 anyway. Its draw is quickcasted crowd control.

Soldier has great DPS true (mostly due to a really dumb design decision with Adrenaline, but whatever), but it isn't immortal. Soldier eventually has to duck its head down. Sentinel has an immortality ability that also functions as a pretty decent damage and crowd control power. In a game like this though, I find the defense more overpowered, on Insanity an Eviscerator shot to the head plus a punch kills the majority of what you fight without the need for massive damage buffs. As for defense, take Praetorians, when they use Death Choir or whatever it's called, and you get hit, most classes die. A Vanguard will just charge after the initial hit and come out ahead. I actually can't remember if you can Tech armor after that hit, but I don't see why not. Hell, backup shielding should take the second hit. You could always stay at range and avoid Death Choir, but weapons do damage based on range.
