Shaman The Windfury Cooldown

The Windfury Cooldown
After WF procs it cannot proc again on either hand for 3 seconds. No 1H weapon in the entire game can proc WF twice in a row. This means that WF will proc less than the 20% promised on its tooltip.
- When only one weapon has WF, each hit outside of the cooldown has a 20% chance to proc. This leads to a 11-18% overall proc rate, depending on gear, weapon speed, spec, and luck. Slower is better.
- When both weapons have WF, each hit outside of the cooldown has a 36% chance to proc. This leads to a 11-14% procrate with weapons faster than 2.0s unhasted and a 14-18% procrate with weapons slower than 2.0s unhasted. Slower is better.
