I've been wondering how many hard AIs on a map with locked teams (all AIs on a team against human player) a good player should be able to fight off by himself. I've done three before, but I got lucky that game. I find it's a hell of a fight to defeat two, and it really helps if I have to defend no more than two chokepoints mid game. I also do best as Advent. If I don't get hammered down early game and get a couple of caps leveled up nicely, I can use the Advent's potent abilities to fight off a superior force.
I play most of these games on Random medium maps. I really don't know what a good player should be able to handle, and I was wondering how well the rest of the Sins community can do in this sort of set up.
