Figured I might as well get this started!
Balance
* Nature's Torment is now named Nature's Grace and now resets the cooldown of Nature's Grace instead of Nature's Torment.
Feral
* Thrash affects all targets within 8 yards. (Tooltip clarification)
* Tiger's Fury now increases physical damage done by 88.8% for 6 sec. (This one is weird, might want to wait before theorycrafting)
* Pulverize base additional damage increased by 66%.
* Stampede now affects your next Ravage. (Tooltip clarification)
* Fury Swipes - When you auto-attack while in Cat form or Bear form, you have a 5/10/15% chance to cause a Fury Swipe dealing 200% weapon damage. This effect cannot occur more than once every 3 sec. / 5 yd range, Instant
Restoration
* Lifebloom can now be cast on an unlimited amount of targets while under the effect of Tree of Life.
* Omen of Clarity (Passive) - If specialized as a Feral Druid, Omen of Clarity will also have a chance to occur from your auto-attacks. (Tooltip clarification)
* Tree of Life now lasts 30 sec, down from 45 sec. Costs 6% of base mana, down from 13% of base mana.
* Efflorescence no longer procs from Regrowth critical heals, now procs when you heal with your Swiftmend spell. Now heals all nearby friendly targets within 8 yards (up from 4 yards) for 10% of the amount healed by your Swiftmend over 7 sec.
* Blessing of the Grove no longer increases the damage done by your Claw and Shred.
I'm just going to start on the tanking perspective, since it interests me the most.
The Pulverize damage increase we saw coming... at least I think some of us did, since the bonus damage was based off of 5-stacks of Lacerate. A 66% increase would bring it in line with 5-Lacerate damage.
With Fury Swipes... wow, that's really nice now. Aside from the 200% weapon damage done when it does proc, the cooldown reduction from 6sec to 3secs (as well as the increased chance to proc) makes it much more attractive.
