Since the 9.1 changes did not help mw get onto par with the other healers. Here are some suggestions, I mean hopefully you read the class forums for input and obviously you won’t want to add all changes people suggest. But here we go.
Since mw monks do 0 damage in pvp since they can’t get into range without being nuked dead or put into endless cc once they step into the open right now. Bring back xuen the white tiger for mw monks like they had in early Mists of Pandaria. It will only last 25 secs but it will be similar to what the resto sham does now with the rock elemental only theirs lasts 1 min whereas xuen will last only 25 secs. I see resto shams doing almost equal damage to their dps in 2v2 because of this rock ele. (Maybe the xuen also heals abit too like it did back then as well).
Take soothing mist off global cooldown like it was in the first 3 expansions mw monks were in. This is a must.
Cocoon in stun (I see every mw monk suggestion change forum always mentions cocoon in stun again like they had before in MoP).
Make demateriazlize pvp talent baseline. There used to be a talent that made mw monks immune to damage for 2 secs in MoP which was baseline.
Honestly the main change is taking soothing mist off GCD, I wish the developers knew how essential this was, if they played in MoP and WoD at anywhere above 2k in arena it was the only thing that kept you alive in fast pace metas like today.
I think you need to look at what MW monks had in the past that could come back and help now. If anyone else has any suggestions to help improve mw, especially with doing ranged damage like all other healers in pvp feel free to comment.
