If you say so I’m inclined to believe you, as it is your post.
But from the 2nd screenshot, Ana very clearly is in your Defense Matrix while alive with about 25 health left.
Her cape is not.
Her cape, just so happens to also not be a part of her hitbox at all.
I understand the desire here, but what this boils down from my interpretation as a higher-elo player is “D.Va needs to have a range increase because my teammates are foolish”. Which… would break the game when you have teammates who aren’t acting foolish, typically in higher-elo environments like scrimmages, tournaments, or the Path-to-Pro.
The screenshots show that there is progress for both teams, meaning this is a Competitive game.
With over a minute on the clock for the attackers, and seeing them have used within seconds of each other: Tactical Visor, High Noon, Primal Rage, and Rally, signifies that this is on the lower end of the spectrum for elo.
In addition to this, your Ana (who died), is standing in quite possibly the worst place a defending Ana should ever be.
She’s in the open, away from her Tankline (which is D.Va and Roadhog), and away from her Brigitte (who is meant to peel for her in this composition, not D.Va).
She is not peeking from a corner as she should be.
Nor is she on the high-ground.
This is dissatisfying for you to see her, react quickly enough, and still be faced with a teamfight loss because you couldn’t reach her in time.
But that is not the right thought process to approach GAME-WIDE PvP balance decisions.
Why didn’t Ana use Biotic Grenade on herself? Why didn’t she sleep the Soldier or ulting McCree? Does she have neither? Because nobody on the enemy team is Anti’d, and no one on your team is buffed. There’s no assist icon from your kill on Zarya, so she didn’t anti her within 5 seconds of Zarya being eliminated.
I understand where you’re coming from. I do.
But look at it from the way I do, or at least try to.
Is this buff really needed? No. You just need a smarter backline who knows where they belong (hint, its in the name).
