I think saying WoW is old is the ultimate condemnation. You don't come back from old..
I personally don't think WoW just is old. I think development stopped innovating, and made some bad choices. This is why I am so critical of the state of the game. I believe things can be done to breath life back into Azeroth. Things like 40 world bosses throughout the world. Slowing the fast forward to the end mentality. Making the world dangerous, just to name a few.
What do you think? Is WoW just old?
edit - I think I should have made the "just" bold. and added a just in the first sentence...
