Reaper is fine.
Pickrate =/= unplayable.
We shouldn’t be buffing around pickrates.
Also, you’re complaining about his spread, self heal, teleport, how armor works for everyone, and his ultimate damage.
The only thing I can really see is armor, because it impacts every shotgun hero too sharply but in order to fix that, armor just really needs a rework.
His spread is important because if you hit all the shots, he does quite a lot of damage (140 per shot x2 shots per second for 280 DPS). He isn’t designed to be used at any range over ~10 meters, simply because the falloff is from 11-20 meters which makes each pellet do 2 damage instead of 7, making his damage potential at 40 instead of 140 per shot.
His self heal is fine. If we increase it anymore, he’d be completely viable without healers. Which is not very good for almost any DPS, especially one that does lots of damage with 250 HP. He’d be near unkillable if we increase his health regen more.
The only thing I can see for his teleporter is maybe making him not say “REPOSITIONING” like a madman every time it’s used. Keep the ‘shroud’ kind of sound effect, but remove the screaming portion of it.
Armor needs to be reworked. It also halves the damage of everyone with a shotgun or that shoots a large amount of bullets with little to no damage which includes, hog, tracer, sombra, torb, dva, doomfist, Bastion, Orisa, Winston, Zarya (almost every tank on the roster was mentioned), Moira, Symmetra, and Mercy. Every single one of these heroes has their damage halved or almost halved by armor, making them do nearly nothing against a hero with armor.
His ult is another thing I could get behind. But the main problem with his ult is how much that can stop it, which can be solved by timing and positioning. We shouldn’t buff his damage on it when it’s meant to kill squishies. I mean, it does make no sense that a tank killer like Reaper shouldn’t be able to kill most tanks with his ultimate, but that’s more of an identity issue than anything.
We shouldn’t be talking about how we should buff Reaper, whom would have no impact on the meta or anything at the moment, when we could be talking about someone who stops literally the entire meta that everyone is deeming the worst thing ever, Sombra.
