Alchemy stones should have their passive effect (Increases the effect that healing and mana potions have on the wearer by 40%) removed in Shadowlands.
Currently the trinkets are obscenely powerful for healers, being BiS for Holy Priest, Mistweaver Monk, Restoration Druid, and Restoration Shaman in mythic raiding. This is because of this passive effect, which grants an extra 10024 Mana (more than five Rejuvenations) when using a Potion of Replenishment.
This forces healers playing mana-conscious specs into choosing Alchemy as one of their primary professions. And this isn’t a new thing. Legion alchemy stones with the Leytorrent potion had this same issue.
I propose that this passive effect should be removed from the already powerful (Versatility + Socket + Main Stat proc) Alchemy trinket. And, in turn, the mana restored by all mana potions should be increased by 20%. Going OOM is no fun but managing mana, especially in progression, is what differentiates good healers from great healers.
