Just a thought, but in Infection, if you kill 10 Zombies as a human or 10 humans as zombiw you level up! Or maybe thats too fast to level up. IDK But comment or do the voty thingy and help the admin choooose!!!!
No support. People can easily farm kills off their friends or afk people in spawn. Plus OP zombies would level up so fast and so easily it would be unreal.
No support. Problems: Is it by level or rank? What happens to someone that is a sergeant major and doesn't prestige?
Support, I feel when your nearing the end of presteging the only way to level up effectively is by voting. I do believe it should change the amount of levels you need by what rank you are. An example is a Rct would only need 3, but a GySgt would need more like 15, basically you need more kills the higher your rank.
