Mistweavers who raid in 25M raids have just received a huge buff to Revival.
Revival now has a healing cap of 15 raid members (up from 6) when used in a 25-player instance.
This change did surprise me, to be honest, as Revival has been a pretty powerful healing coolddown to use in raiding this expansion. But Tranquility did also receive their own buff, so it could be related.
Now, will Healing Tide see its own buff as well? Nothing yet, but it wouldn’t be a stretch, since it only heals 5 players currently per tick.
