Thing is for example I still remember blood raven from D2. That was scary how fast she was moving just charging out of nowhere. I remembe the dark maps where you couldn't see very far. I remember the poison boss how epic was it to kill her. From D3 ... what's memorable about that game. Honesly the story tomes dropping ... that is the most interesting thing I remember. I will go ahead and say that storytelling in D3 is great. The story is very bad, but the story telling is top notch. And the combat, if the spec you like is decent the combat is good. Not exciting, but good. Still it's mind boggling how many blatant mistakes Blizz was able to make in that game. And the patches do improve the game, but come on Blizz ... why do you work after game is released. Most ppl are done with that game now. It may generate you more money, but it trashes your name.
The saving grace of Blizz is as for the last few years ... lack of competition. But ... we have POE and TL2 to fight D3, GW2 to fight WoW pvp and I hope some MMO to fight WoW PvE in the future as well.
