actually, I believe that Blizzard has gotten more user-friendly since they merged. Granted, the realID thing was a load of sh*t, but they have been releasing extra content for Diablo and Starcraft over the years, and have facilitated some stuff (like providing customers who register their CD key with the ability to download the game wholly from the blizzard website, which was handy for eee users. Or the no cd patches.). Pre-merger blizzard never did this kind of thing. All in all so far I am not dissatisfied by blizzard (so far = starcraft, Diablo 2, warcraft 3). I even bought original warcraft 3 after having pirated it (granted, installing TFT was a factor, but still, I bothered). And I assure you this is not something I do very often.
I cant talk about starcraft 2 yet, because I am not buying it anytime soon (eee computer). When I finally do I'm as likely to buy it from the bargain bin as to acquire it through the Bay (and, like in WC3, if I like it I might end up bargainbinning it afterwards). I dont like the stuff I am hearing about realID and that kind of thing, though, but I was never a big fan of multiplayer. I like being able to play without relying on my net connection, or other people.
