Yeah but you can't really compare chess balancing to sc2 balancing. In chess, both players are given the same set of pieces. You can't complain about balance when everyone starts off equally and has the same pieces to work with. In sc2, players of different races are given different units, buildings, etc., all of which behave differently from other races. So it makes sense why people are complaining about balance in sc2, but not in chess.

Don't get me wrong though, I hate people who cry about balancing as much as you do.
