Concept: Parties are to vote on one another of who "Pack Leader" should be. Simple keep your leader alive and kill enemy teams leader. As long as leader is alive members of that team will be given a 5 second respawning timer. Once leader is down he/she will have 1 remaining life while "remaining" teammates will not respawn.

General Tactics
TANK: Obvious choice for the long lasting punching bag but can only live as long as
-HEALER is ABLE and AROUND for them to do their duty-

DPS: Risky choice but a clever deception against those who seek their targets who are passive but take note of how much damage either DPS can manage.
-A DECEPTION tactic to buy your team time to seek the others leader-

HEALER: Classic choice who distributes heals throughout the team. Only through observation of the enemy team if both DPS and TANK were to go down the only remaining target the enemy team can focus is HEALER.
-RACE against TIME is the tactic of a heal leader-
