Sweats wiping the lobby is ruining this game

I loaded into De Dust today to play and ofcourse a bunch of sweats playing as a team are roaming around the map just killing everyone. And when they kill you they load in next round with OP armor and guns that one shot me.

I dont even get a chance to plant the bomb?

How is anyone gonna start playing this game when the no lifers just kill everyone? This game is dead, Bungie should add a story based single player campaign, I actually want to learn more about the Terrorist lore.
