Those figures sound a little off to me.
Only 1/4 of people refusing to play because of the lack of females? I call hax.
What? The OTHER numbers? No, they're fine. >60% Operatives is totally reasonable and justified. And sidearms have been made pretty OP since the game was released 3 weeks from now.
The other numbers are fine? Are you joking? 34% (or whatever it is) for sidearms would be more realistic if it was only talking about revolvers, with at least another 25% using machine pistols.
Operatives should probably be higher also, as they're basically Jack Bauer/Jason Bourne/James Bond meshed into one persona, and considering each of them has killed enough to people to start an army, imagine the damage EIGHT Operatives could do. Especially if they each get their own Aston Martin.
Though I will say, you're probably right about the whole female hax thing. I know I won't be buying Brink because of it - I just hang out here because it's cool. That, and because I love voting in the immense amount of polls asking what body type, faction, or class everyone wants to be.
