I do, as there's not all that much to do in the beta (won't keep you playing every day for weeks) and I'm sure they still need to do proper stress testing but its not the same as Diablo 2 or SC was. Nor will it ever really have the same scale beta as D2 did.
What annoys me thou is why can't they just come out as any other normal ppl or developers and just say, "look this is what we doing or planning to do and this is +- when it should happen".
But rather they go around pissing fans off immensely and trolling official forums. (something you'll realize if you frequent the official and big fan site forums)
"Aaa whatever, ppl going to buy our awesome game anyway, we are Blizzard and this is Diablo" attitude. The hype is so much and fans are getting really really annoyed. Well that's the feeling I can from all the difference sources I frequent anyway. Maybe I'm wrong.
@Oculate, its not about the US server in that regard, there's one Beta or development server (Blizz Irvine). Whether they will do a testing when all regional servers are up I don't know. There has been no indication regarding that.
