No, you don't.
Having attended their convention last year, I can say with no regrets that they're so bad it's not even funny. Yes, some of them seem to be okay - but one salary increase = leaving the development of WoW to morons like GhostCrawler. Ever since Ulduar the game has been in complete and total decline. If you were there for the panels on Diablo 3 (I've yet to release my footage) you'll see that they had two fucking points to make with the Demon Hunter class - they wanted her sexy and GRIMDARK - yes, they actually said GRIM and DARK back to back.
During my play time with the demo, I zerged through shit as a Warrior/Beserker/Whatever class I played. Fucking plowed through that shit with no skill whatsoever. Chug potion, BLAM BLAM BLAM, chug potion, run run run, BLAM BLAM BLAM, chug potion, BLAM BLAM BLAM. Blizzard has no right to say they make ANYTHING even close to an RPG. The last good game I played from them was probably Lost Vikings. . .
