Honestly, I hope I never get to the point where I can't live without online for two days. Personally, I can't sign in at all but I'm not being a little b!tch about it. The only part that does annoy me is that I can't play any free PS+ games because it thinks my subscription is expired.
At least you're being told in advance. It's not like you try to sign on and they're like "whoops, sorry, we're doing maintenance today. Surprise!". Maybe plan to do something other than complain about how you can't play online? I do realise that it's gone over their estimated time frame, but it's not the end of the world.
(On a side note, I can't wait to see The World's End.)
Anyways, at least get off Twitter, I'm tired of seeing your angry tweets because you can't "shoot some [insert word that I'm too white to say]" and that you're now going to buy an Xbox. No one really cares. Not I, in any case.
