The beta rocks
Terran suck as usual
Protoss can no longer seduce other races
Zerg are based around rushing with multiple unit types now

Dood, a good terran player can have 8 reapers in your base within 5 minutes of game start. You need a pretty big/fast army to catch 8 reapers, especially when they can just as easily split in to 2 groups of 4, 4 groups of 2 or 8 groups of 1.

Many times I have won games simply by microing forward and backwards taking out 1 worker at a time, or hitting 1 shot on the enemies troopers, or 1 shot on a pylon. If you follow a reaper, you won't catch it and another reaper will get you, if you don't chase then you will be ignored.

Terran is pretty good at rush IMO, because they have a good mix of versatile and specialist troops. And they concentrate a lot on movement.
Maybe you can deal with a reaper rush, but lets see you hunt a ghost, a reaper rush, and a viking raid.

Terran is very receptive to good micro I find n_n


Zerg is epic fun, 10 hatcheries and you can pretty much fill up your supply limit within 1 spawn's time.

Protoss is classic, rush their base early with a probe, drop in a pylon. Then drop in a cannon or 2, and maybe a gateway if you are feeling like a super douche. Ah, good times XD

Terran dont suck. You just have to know how to play them like the other races. I can beat the Protoss AI with the Terran(make LOTS of bunkers, like around 20)... then again I can beat the AI in any combination.
