I think that alot of people would like to have new races to explore so much that they wouldn't care if its balanced. Blizzard wants to keep its 3 signature races fair and balanced. I say that a compromise would to have Zerg, Terran, and Protoss balanced well as the "Major Races" these would be the most powerful races in the game. In addition there would be "Minor Races" to play. These would be varied in how strong they were but they would all be much weaker than the major races. What do you think of that idea?
