This is a serious question. I hear how busted from EVERY role x support ability is. So to list the most common ones supports shouldn’t be able to:
-Stun
-Sleep
-Boop (unless it’s Lucio)
-Life Grip
-Resurrect
-Have a barrier (I’ve heard this for both Brig and Symm)
-Damage boost
-Have/grant immortality
-antiheal
-Have threatening damage
-Cleanse
-Burst heal
What, then, can a support have? What wouldn’t be a busted ability for them?
Only speed boost from Lucio as its completely benign and does not effect the enemy team at all.
But it affect how fast rein will smash off someone head with his hammer, what people does not like much.
I don’t see many people complaining about Petal Platform and Tree of Life. But I imagine that’s because Lifeweaver is really bad right now so they’re inconsequential and don’t “get in the way” of DPS/Tank kills.
-Discord
Are the five that are problems. The rest are fair and balanced. Nobody complains about the rest.
You should change your title, every CC ability is instantly made toxic if you crouch a lot after you do it 
Tanks will only be happy when they have no counters at all.
DPS will only be happy when everyone they look at dies.
Supports will never be happy. OP or weak, it’s all irrelevant. Our suffering comes from the players not the game.
Ya a no cool down boop is annyoing.
You forgot discord
The only “toxic” thing in the game is anti, because it disables a complete role main existence reason. The rest is fine.
Discord also does that
Discord was fine before and would be fine again if dive wasn’t so neutered by the developers. As it is now, Zen can pretty safely sit back and not feel pressured in most games.
No it does not. It does nothing on its own and has to be used by people to get value. If you discord and not hit the target, nothing happens. Anti is just everything in one go: damage, heal, heal boost, and anti in one go. If people complain about suzu, but not anti, then they are lost. Suzu does heal and provide immortality for 0.85 seconds, while having a higher cooldown…
the problem with discord is 1 less tank not dive
it removed the tanks ability to do their job permanently
You are correct. Let me adjust that.
Supporting is toxic?
You take these away and they’re just healers. Like, actually. They wouldn’t have much else to do.
Yeah, you even said
lmao then what are they after that?
Reload that’s about it. 
So here’s the problem with these abilities: allot of them are on too short of a cooldown and or AOE. Anti wouldn’t be broken if it effected one person, had a longer cooldown and didn’t do 80 damage? I actually don’t know the # off the top of my head but it’s high.
Some should however be changed completely because I don’t think some of them should have existed (suzu)
People complain about Bap, Kiriko, Ana, and Zen’s damage all the time. EDIT: Brig and Moira, too, but them simply existing garners complaint.
