First off: I don't know where this would go. I thought about exploits, it's kinda a tip/exploit, but I put it here. Also: This only works about 99.99% of the time, sorry.
You could use this if you wish to show off to your friends, you know, screening 500 of you topping the damage by tens of thousands. I havn't tried this with any other class except a Warrior, and only on Horde.
It is very simple, all you have to do is go into the mines... and start killing things. With my warrior I'm getting white crits for 1.1k, MS crits for 2k... After I have cleared the whole mine, I cap it, and move on to the next one. One game I had 250k damage done, about 20k above the next highest, a lock.
If you feel like showing off to your friends, or mabye even if you're selling your account and want to "show off your gear" because you hit 1st in damage. Or if you want to make a PvP vid of you owning the damage charts, this is for you.
That is all.
