Choosing a Healer for Mythic+

[MadMilitia]

The information is a bit skewed in favor of Resto Druid / Holy Paladin and it's not apples to apples but this gives you a high level overview of what works for comps based off everyones logs.

https://bestkeystone.com/#/compositions

Your able to sort by Tank / Healer and see how they all perform - what % the keys are successful... and yikes. After looking at the information the Prot Paladin is the worst matchup for a Resto Shaman. (maybe I need to rethink my comp?)
.. looking further the Mistweaver Monk is the best healer for a Prot Paladin. (Based off of successful keys).

HMM!

Thanks Ellay, this confirms my suspicions about the resto shaman healer in BFA.

First Brewmaster for the reasons stated:

1. Stagger mechanic smooths out big spikes which RSHM has trouble with.
2. Poison / Disease dispel which RSHM doesn't have.
3. Excellent mobility which RSHM cannot help with.
4. Knockback with ring of peace.

Then what supports go well with Brewmaster, to fill further gaps

Fury

1. Piercing howl AoE snare and pure phys for Brew's mystic touch 5% phys dmg
2. Battle Shout damage buff
3. Excellent cleave

Beast

1. Traps
2. Ranged spec with excellent mobility
3. Enraged dispel with spirit beast

Outlaw

1. Shroud
2. Excellent cleave
3. Good utility in kicks, blind and gouge

If you prefer RSHM for M+ this is the best comp to run, by far and the stats on that page illustrate it. I also suspect Brew / RSHM / 3* BM is also powerful but not as good.

point 2 .. if you have paly tank you have that covered. point 3 Riptide heals well..combine that with traits that make your super fast surge heal bigger and spritwalkers grace allows you to cast on the move. And shams have tremor totem to remove fear effects! But yea..might not be as good as Monk..one of these days ill try one 8)
