I have played my league placement matches as Protoss and been placed into the Gold league. I have played 3 or 4 games as Terran and Zerg combined, so I have next to no idea what I'm doing with those races. If I were to play a 1v1 league game as one of those races, would it count against my Gold league rating or would it be a separate set of placement matches as the new race?
I know you can be in multiple team leagues at the same time; I am currently in 2-3 2v2 divisions, each with different teammates.
