Earthshaker?

The point of the bad ratio is it increases the chance of the proc per swing. Specifically its large delay does. Proc rates are measured in procs per minute. The faster you swing the more swings per minute and the less chance of a proc per swing. Ye olde shakerpage formula was for you to take off all your haste items and duel a shaman and get slowed. This meant that you had almost 1 /4 chance to proc per swing given how slow you were now swinging a 70 delay weapon. Combine that with rampaging at 40+ targets at once and we get about 10 procs per swing, that is 2,500 damage, double attack and its 5k, triple (warrior with aa remember) and you had 7.5k. More mobs = more damage.

Win, collect AA, wait for respawns and AA to refresh.
