Absolutely no one wants to do ANYTHING that would make the game less statistically balanced. I think this is flawed thinking, because very often newer players are on the human side, so there may be less skill on one side or another, but the game mechanics give that side an unfair technical advantage, so it comes out even anyway. The point isn't to Marxize away all possible differences in player skill by compensating with race characteristics. It's to make totally even gameplay totally even. But it's incredibly difficult to do that, since the two sides are totally different.
We ought to be able to try things without getting called out on skewing the almighty win/loss charts. At the very least, test servers running "beta mods" that change the gameplay, not just beta maps, should be up and running to get feedback for changes before implementing them everywhere.
