Read again. You make no sense unless you really are so naive to think things can be perfect from the get go.
The game may have all those years in development, but this is an MMO. They have to keep improving the game as long as the servers are live. That's how things works, for ANY MMO. and to be honest this is the smoothest launch I have ever been in. The game has been perfect for me.
And regarding WoW. I had so many automated messages answering my tickets That I would have played for free, all my 6 years in the game, if they gave me a quarter for every one of them. The most resent one not 2 weeks ago.
They just recently fixed a bug from the first boss in BWL, and was there since they first launched it. That's roughly 24 hours, right?
So, if you like the game, keep playing, report any bugs you encounter, and have fun.
If you don't like the game, I'ts your time, your money, if you like wasting it is up to you.
