Legendary Icy Burst and Flamespear now have a .5s ICD
Legendary Rift Burst buff reduced to 65%.
Legendary Viral Stream - Damage increased by 20% per DoT on target.
Legendary Dire Blow - Damage reduced. Now correctly scales with Attack Points as intended.
Legendary Rising Waterfall mutlihit chance increased to 40%.
Legendary Alacrity 3rd attack chance increased to 75%. Also causes attacks to deal 20% less damage in PVP.
Legendary Shock Pulse now has a .5s ICD
Legendary Skyfall damage increased substantially.
Legendary Double Pulse now triggers 3 1 Point Skyfalls.
Not sure about balance changes to other classes, I also haven't really checked tooltip numbers or talent changes, but this pretty much kills the warrior. We relied too much on atleast shock pulse in every DPS spec.
Edit: Thanks to DarkDaemon for some more changes. Tempest hype!
