You know you have made a good distribution of the nations when both sides are complaining about the nations they've got to use
I think it is good - the blood nations are evenly distributed, team B has perhaps the stronger races on balance, but none of them have anything strategically or tactically in common with each other. Team A on the other hand has less powerful races which will work together more smoothly.
I assure everyone though that the races were distributed by the random generator
