Instead of testing individual players' abilities, you goal the boss's DPS. So you get guys that don't care about ads, reviving - socialpathic gamers that are not team-oriented (crucible mentality, not pve) that make the game not fun like it was years ago. Test on ability, not your game, but the team's game - not just boss dps, not just speed, but finishers, precision, revives, giving shields - real team pve attributes.
