Yeah, it was tough for me, but being free of that game feels so good... and now that my account is sold, I don't really feel like starting from scratch when none of my friends are playing, or paying for a new copy of the game plus the monthly fee...
I'm really liking Diablo 2 right now though. You should check out this mod I'm playing for it, it might ween you off WoW haha. It still feels like D2, but it's a whole different game. The character classes are completely revamped, with brand new skill trees, specialties, etc. There's special "uber talents" that you can only get by completing certain quests. The monsters are harder, and have cool/unique abilities that make them way more fun than in the original. The items are all new. He even added a real endgame. Like this guy basically devoted six years of his life to making this thing. Blizzard is even using some of his ideas in D3... they don't even know how he did half the shit. It's pretty awesome. Here's the link.
