The only thing i dont like is how there are no medics, and only medivacs... it does change the gameplay a lot, but i dont use terran anymore since i've seen the wonders of the protoss.
I always liked the toss in SC1 but they just plain dominate in SC2.
if you'd like striker, i can pm you the code for one of my guest passes and you can play online, or do the SP for a few hours?
