From what I have heard, if you are a power gamer who is all about the race to max level and how much "Phat Lewt" you can find, then you will hate the new on-line D&D game.

I played most of the games, EQ, DAOC, WoW, COH etc... my WoW account is still active but I rarely have time to play anymore.

If you liked AC you would probably enjoy WoW more than D&D, just depends on your play style.
