this is what blizzard calls ballance: the stats were taken from tournaments globally over the past year as you can see terrans have been winning in a huge ratio over the other 2 races and zerg is devastating protoss in summary: T>>Z>>>P http://i.imgur.com/cGzPj.png it's pretty clear that protoss needs some work while terrans need to feel the nerf bat a bit
to balance a game like SC is pretty hard you know you cant just NERF someone because their blue bar is longer and well when the expansion comes out they would have to start over because they are adding in a few units oh well
Doesn't seem that bad when you ignore terran and also realize this is year worth of data (SC1 had 10 years ). I suppose they could just tone down terran a bit and buff T vs Z but that's easier said than done.
I think this is intentional. They need to create openings for new units in Heart of the Swarm. Aside from patch balance, right now I would say that Terran has the most options of all three races on how to approach a game. Players are only now beginning to fully utilise this to their advantage.
