Our 51 pt talent, it is basically the same as a warrior's whirlwind ability except that DS heals for negligible amounts. Despite it seeming like an underwhelming talent it is critical to our DPS as it can and will trigger seals and RV. This skill is normalized to 3.3 weapon speed.

but it could be wrong
Cwow (patch TBC 3.13 ï¼Œdamnã€‚ã€‚ã€‚ï¼‰
The Test Sword(Faster and Higher DPS)
The Test Hammer(Slower and Lower DPS)
Recount ï¼šDivine Storm By Using the sword
By using the hammer
You see?Though the hammerâ€˜s ILV is lower than that of the swordï¼Œthe damage is obviously higher.
Do the Same test In TWOW(Patch 3.22)
the conclusion we reached that is "Divine storm is anomalistic to 3.3 weapon speed,tslow weapon can deal more damage."
