That’s… the role of a healer, yes. Either be healing, cleansing debuffs, or providing life saving mobility to the team.
I still think Blizzard needs to add more ways for healers to support their team that isn’t just “help out with damage until you need to heal”.
My whole problem is that that’s just not interesting gameplay. If I want to deal damage, I’ll play DPS. If I want to take all the aggro, I’ll play tank. If I want to keep the team from dying, I’ll play healer.
