AFAIK, the beta isn't covering that, but general game balance. The noob welcoming features, like special challenges (win by rushing, win by bunker creep, get expansion up under 4 minutes, etc), don't need to go through public beta testing. However, you can play in "Novice" maps anytime, where there's barriers that seriously delay a rush, and allow you to understand the tech trees and unit abilities better. I think Blizzard should made perfectly clear that what's being tested is the end-game, the stuff that will keep SC2 alive for many years: balance. And of course, system stability. I agree with who said that the author isn't a serious RTS gamer. While you don't have to play SC1 to give an opinion about SC2, I think having played some sort of RTS consistently and competitively is mandatory. No, having finished SP campaigns doesn't count, neither does a "few games with my buddies". Or if that's all that you did, then you're only equipped to give an opinion about those aspects. I'm in the beta, and I've felt underwhelmed with SC2, especially after having played so much DoW2 online. (HUD, 1/3 of the screen, rly needed?). But I've given it a serious try, and while I keep getting my ass handed back to me in tiny pieces, I'm discovering a whole new game. Once you get past the sameyness, you understand why so much has changed and remained the same - because it has so much depth already.
