The only thing I don't understand is 'required micromanagement' being considered a weakness for Terran. Micromanagement I thought would just be that universal thing for all RTS's. Eh, not a big deal though.
As for beta, I wonder if we'll be able to discuss all aspects of beta here. I forget what it is called but in some games you lose your beta account if you give away too much info, but that may be for some games only.
Protoss look nice, but I believe in STRENGTH IN NUMBERS, THE ZERGS~!.
I don't think I ever enjoyed playing as Terran because they just seem so generic imo, not imbalanced, but not really my cup of tea I guess.
