Zerg SUCK simply for this reason, its not hard to own with them, i mean come on grab the second thng on the drone building creation list (Hydralisk den) and make one of the first things on it (Evolution Chamber) then make 6-12 hatcherys and pump hydras how hard is that? the other races actually require a little bit of skill to be good with. But thats just my opinion so dont flame for it
