Quite a lot of specs gained a number of abilities/keybinds that they can talent into with the new trees.
I think my Mistweaver got 6 for example from a PvP perspective.
Can now take all of Healing Elixirs, Dampen Harm and Diffuse Magic when previously could only choose 1.
Can get both Ring of Peace and Song of Chi Ji instead of 1.
Gained a slow and kick.
