Because Ret Palas should not be able to do 271,000 dps on Heroic Ultraxion.

Basically Ret Palas got broken and did insane levels of DPS until the rolling restarts. The above WoL files shows 3 ret palas pulling a combined 561k dps in a 25 man raid!
Got to love Blizz and their pre-release code testing!
I heard they did this for Hal so he could do more then 9.2k dps for once.. To bad its getting rolled back so soon :(
haha I do more then 9,2k dps even as tank hubbah :P and I'm not terrible as retri dps :P
