Idk, I think you really just gotta buff rsham mana again. Healing feels pretty solid when you can cast, but you just oom if you do right now.
I know rshaman mana WAS oppressive where you were so efficient that other healers would drink twice to match your one bar, but I think we shifted too far.
I also don’t think you can really buff instant cast healing, since there’s already so much and mastery scaling is so good.
Imo buff mana and give a pvp talent that makes earthen wall centered around your target woth earthshield. That could make ES unpurgeable while it’s up too.
