So I've tried looking through the internet for a few specific things related to gearing for Proving Grounds Endless as a resto shaman.
The main bit of information that I found was "I went for first haste cap for riptide tick, then crit>spirit>mastery>haste, int flask and food. I was nearly oom at the end of 9, 19, 29 waves so mana regen was spot on. I used unleashed fury to heal virmen dots easier, some people use primal elementalist for extra damage, remember to use stormlash, i used it on wave 5 and 10th (with mages hero, didnt use hero myself to save mana)." by a user called melzas in another thread.
The main thing i'm asking is if there is a list of gear that is best for proving grounds, or if it more comes down to individual playstyle?
