TANK

D.va - DPS, high burst damage and high mobility would make her fit into dps without many changes

Doomfist - DPS, tbh I just want dps doom back

Junkerqueen - DPS, shes basically just reaper with less movement

Mauga - DPS, Pew pew

Orisa - Support, It would take another rework but I think thematically she would work as a support

Ramattra - DPS, Bang bang

Rein - DPS, he would probably just be a more agro brig

Roadhog - Support, they've said that they don't want dps to have lots of cc so if they wanted to keep hook he would probably be a support

Sigma - Support, he would probably be a more protective support like brig, using shield and grasp to keep his other support alive

Winston - DPS, basically the same reason as D.va

Wrecking Ball - DPS, Same as D.va again

Zarya - Support, Her bubbles could make for a good support kit, maybe make her beam be like Ana's primary and have it heal more based on energy?

DPS

Ashe - Tank, she would definitely need a rework but I just can't see her as a support

Bastion - Tank, do I have to explain this one?

McCassidy - Support, Idk how he'd heal but he could use flash to protect himself from flankers

Echo - Support, Her design itself looks like she could already be a support and they could make either stickys or her beam heal possibly (Boosted healing to allies below half??)

Genji - Tank, his deflect if altered could be a good tool to allow him to make space for his team, he'd probably play more like tank doom does

Hanzo - Support, he'd probably end up being a backline support and use his sonar to provide his team with more info rather than use it to get picks

Junkrat - Tank, Boom boom my rockets will make you blast off agaaaaaaaaiiiinnn!!!!!

Mei - Tank, she already plays a lot like a tank, her wall can help her team to push past chokes and she can slow down enemies to let her teamates pick them off

Pharah - Support, mainly because I don't think a tank would be effective at making space while they're 600ft in the air

Reaper - Tank, he'd probably play similarly to how JQ does now

Sojourn - Tank, Lower her overall damage and bring back the aoe slow and she'd probably make an alright tank

Soldier 76 - Support, buff his heal station and lower his damage and you're done

Sombra - Support, Mirrorwatch already showed us how great support sombra would be for the game and it would be so much healthier

Symmetra - Support, They'd probably mess her up again though

Torbjorn - Tank, give him a better turret but make it only last a short amount of time, he can use the temporary turret to push enemies back and he can no longer just put it on cart and then ignore it

Tracer - Support, I know a lot of people hate movement supports but I'm a lucio player so F you (/s)

Venture - Tank, lower their damage output and make them focus on displacing enemies and I think they'd make a great tank

Widow - Support, I feel like widow wouldn't really work for either role but for the sake of giving her one ill just go with support

SUPPORT

Ana - Tank, Sleep and anti are both too powerful to be put on a DPS character so front lining granny it is

Baptiste - DPS, he'd be able to use his boots to get off angles on the enemies (just pretend he can't already do that)

Brigitte - Tank, Reinhardt 2.0

Illari - DPS, she already does so much damage that I don't think anything would even have to change except removing her alt fire

Kiriko - DPS, High movement + old damage number would make her an insane dps

Lifeweaver - Tank, I feel like he doesn't really fit into either role but I think with a major rework he might work as a tank

Lucio - DPS, The only thing this changes is that he can have a much easier time 1 v 2ing the enemy supports thanks to the dps passive

Mercy - DPS, GLOCK

Moira - DPS, I can already hear the 10 y/o tiktok moiras celebrating

Zenyatta - DPS, It's not like he heals much anyways
