3 shots to kill a sunbreaker standing in sunspot and you still have 3 left. Of course you won't kill a warlock with an overshield with 1 shot but that's the tradeoff. Maybe like 200 damage so the only way to survive is to have some DR/overshield or be a max armor striker/ram warlock. They can actually make a separate exotic without touching symbiote as it is right now.
