i think a cool idea as an addition could be the addition of a medic. every team has one medic who is chosen at random of all active players and when a player is ko'ed, the medic has the ability to revive a 5 players for the duration of the war with a 1/2 regen and when a medic is ko'ed, he loses his revive power.
Why dont we give everyone the ability to revive anybody they want 20 times throughout the duration of the war, at 100% troops? That way we can all be winners!
