In the HEROIC version of Deadmines there is a cannon that can be controlled by players. You can some of the bosses back to the stationary cannon and kill them with near crazy dps!All you have to do is kyte them to the cannon and AoE down any percentage of the instance, as long as the tank can kyte them back, the possibilities are endless! This means you can take fresh level 85s with bad gear, use the exploit with the item level to unlock heroics, then go into heroic deadmines and kill the instance and all bosses NO PROBLEM! Additionally: the cannon acts as a feign death, so you can also just hop inthe cannon if you're going to wipe and avoid death.
