Does the random choice of faction count twice in the achievements?
So if I get randomly assigned to the Zerg and win my match, would this count as a victory for both my random and Zerg achievements or just for random?
It does seem so.
I play random and got an achievement for 50 wins as random as well as the 10 wins as terran, zerg and protoss achievements.
Yes it does count. I play random all the time now and a win as random counts towards the random achievement and the race you were given. This isn't lag or a bug.
