Here is one that has been talked about for a while now and we finally got around to getting an implementation out. Boss owners are now able to enforce Boss Helper Max Dmg each time they start a battle with a new boss. The control is currently on the lower left of the boss view under "Helper Max Dmg", dmg defaults to max boss health and min is 1 / (num helpers) * max boss health to spread damage across all evenly. This will not stop helpers from going over the max dmg, but once a helper has done more dmg than the max they will no longer be able to attack your boss. Give it a shot and let me know your feedback. This should come in handy for the Aurora Glacier coop that should be released tomorrow.
