So not nearly as drastic as I thought.
Still, it brings up the question, I feel - Should normal players be benefited in unit caps somehow because of the champion players?
Say I am hosting a game, and I am the only normal player amung 8 players. I still have to contend with 1x unit caps all over the place, despite having about 3x the ai strength for waves? Its a somewhat extreme case, and in theory 7 champions should counter the effect of having three times as many waves.. But I dont know.
