LF resto druid solution. i do fine in dungeons with my current setup. but it bugs shit when i try it in proving grounds.
Just yesterday completed endless using Oracle II resto (enable proving grounds option). I tried Tuanha's and Leaves (using the proving grounds rotation) and had no luck with them. Even if for every other scenario/dungeon/raid they work flawlessly, I couldn't make them heal properly on Proving Grounds, couldn't even pass bronze, they let the npc's die everytime.
iLvl 610 Resto Druid with Tuanha Routine set to PvE mode managed to do gold whilst I made a cup of coffee...
