Zen heal question

I havent played Zen in a long time. So now I noticed this about his healing.
Our tank was almost never topped off cause he was taking huge amounts of dmg. So I thought well i dont even need to switch orb. outcome was that i had like 1/3 less heal than our Juno even tho I was healing the max possible amount as our tank was basically never topped off (and i had i think 2 ults per round).
so is zen heal just kinda low?

And is zen even playable in todays mobility creep as he has zero?

Yes.

His heal is low, because his damage and discord are so good.

You’re really playing Zen for discord and getting picks, trying to build the ult as fast as possible. So leaving heals on the tank is a smart idea.

Very much so. He’s probably not the best option. That’s probably still the Illari Bap comp. But he’s a solid pick still because of how much extra damage he brings and how powerful discord still is.
