i think the title says all.
Shadows just need a hard dps buff or something like a "burst cd" .. ( and PI is not a cd .. its just a joke )
On the same iLevel or Gear-base you will always lose the dps raise because at the beginning you have no good cd ( if you can't start with 3-orbs ).
So firemage/shamans/moonkins just run away ...
like every content .. sp is just a support class
and for the flaming bots : eu-arsenal ( Jessìcà )
