Good, that’s the literal point of the hero. Both Geoff and Jeff have said Mercy is supposed to be, and I will use a literal quote from each:
and from Jeff:
. We want the top two things you notice about Mercy to be, “Oh my God, she’s an amazing throughput healer,” and “Wow, look at that mobility, she’s just flowing back and forth through the map.”
Mercy is supposed to be the standard for highest amount of sustain as she contributes 0 damage and has no AoE healing abilities. She’s a purely single target support hero who has to focus on one person and can’t multitask while healing at all:
The fact that for the last 2 years Mercy hasn’t been seen as a main healer anymore, despite being THE best healer in the game at launch for 2 years, shows how bad the sustain/AoE healing creep and damage creep had gotten until they started nerfing all of it recently.
