I've stopped playing The Feast because...
Of this situation.
Win game whole match, but unable to close out because it is extremely difficult to kill a tank when the respawn timers are so low and the enemy team sits in their base to cheese respawns.
Last 30 seconds of the match, enemy melee LB's person with most medals. Enemy tank picks it up and runs around, using their invincibility CD if things get hairy.
The bad team now wins for exploiting a terrible system that is supposed to be competitive.
The underlying issue I have with the game mode is that for some reason it punishes good players and rewards bad players to make it "fair". Honestly, the only fix I can see is a nerf to melee LB. Make it not scale off a damage increases from Heavy Medal.
