Please get rid of role experience.

Draschel:  I understand. But TF2 is vastly different with a vast support cast not really seen in world of tanks. Support caste in WoT, such as lights and SPG, can be vastly more in themselves, as opposed to medics or engineers which rely on third party. World of tanks doesn't have engineers or medics. Take TF2, and remove the very supporty* spy, engineers, medics. Would the game be vastly different only snipers, soldiers, heavy, pyro, grenadier?
