Can we acknowledge the S9 changes as a failure?

I'm excluding self-heal from this.

Speed Ring D.Va and then Juno/Mauga Meta both had insane sustain, especially with tanks having -9 on armor at one point + the headshot passive. Juno/Mauga meta had the sustain be so bad that Tracer wasn't worth playing. Burst damage was the only viable solution to kill things so Widow started becoming extremely strong. Current Sombra rework is another example of insane burst damage. Hazard completely deletes anything he looks at and lives with 5 people shooting at him.

Plenty of heroes have been left in the ditch since the changes (Soldier, Illari) and it takes them months to make adjustments to make those heroes feel good again (Hanzo, Junk).

It accomplished none of its goals and just made aiming easier and reduced movement skill expression + created the conundrum of hitscan heroes being terrible since they're so "consistent" by shooting logs.
