There are better ways of balancing sides. Perks are hard to come by and that makes them worth something. Lets keep it that way!
All the more incentive for a person to switch to the low numbered side. And for some players, perks are not that hard to come by. But for the guys that perks mean something for, or the I wanna fly for the winning (high number) side it may swing their position.
As for the better ways of balancing sides.......that would be what? Perhaps being slotted to the low country when you log in?
Getting more perks fighting for the low number side as it is now is somewhat esoteric. Little Jimmie knows he will get maybe a vague number more perks being on the low side. But tell him it's good for 25 solid, known, perks and he has something he can sink his teeth into.
Look at what happens when the map is won. "Ohooo, 25 perkies! " always comes up in the text buffer.
