Why are you all whinging and bitching that there is going to be a Day 1 patch?
They are going to be patching the game throughout its life, so what difference does it make that they bring out a patch sooner? At least they are fixing bugs etc that are being reported and they find rather than wait to release a patch.
They probably found these issues after RTM.
Oh wait, I'm sorry, FIXING something must mean it's a bad thing.
