I couldn't say enough about Gundam Evolution in terms of its unit balance, because I'm not good enough at that sort of game. What I can say though, is that it did not have nearly enough variety in its match types, and that its system for judging winners was absolute bullshit. Everything had to be by a system of points, when for things like base capture, "Time Taken" should be enough of a reasonable judgment to decide a winner; instead, my team could take the base in 3 minutes, while the next one could take 12 minutes on their turn, it's a tie, go to tiebreaker.

Like evilplushie said, Gundam Evolution killed itself.
