Ok so as a doomfist main/onetrick 90% of the time. almost every support has at least one way of countering him so I’ll give u a run down.

Ana- legit counters every tank so self explanatory just hit your sleeps and anti anytime he’s low

Bap- can duel him pretty easily and if u are about to die just lamp first then use ur self heal once the lamp breaks to give you the most time ( this is mainly bc doom can stun you if you try to run or jump out)+ window turns him into butter

Brig- she’s the anti dive support so proc inspire on him as soon as possible in an engagement with your flail and try and hit your bashes as he punches which will stun him like rein

Lucio- kinda a hard matchup both ways just stay off the ground and don’t get too close not much you can do 1v1 but can be useful in saving teammates when they get dove just boop him when he goes for a punch and he will prolly miss+beat is super good just don’t get stunned.

Kiri- I mean do I need to say more just don’t duel him it won’t work unless u hit almost every headshot.

Lifeweaver- he’s weird but once u get used to positioning around doom it’s nearly impossible for him to kill you. Save you dash for the heal when u get dove and always keep your petal on cool down if he uses slam just go up and he can’t touch you

Zen- kinda the weakest but also the strongest. You either have to hard focus the doom and do enough DMG before he gets close to stop him OR coordinate with your team to fry him with discord when he dives. A good zen wins against a doom Everytime but u are super super diveable so position smart.

Mercy- stay off the ground. Gets used to waiting to use rez until immediately after he punches or he can stun it out. It’s also nearly impossible to kill an ulting mercy without charged punch and if u sit in the skybox ur probably chillin

Moira- she’s probably the worst outta the bunch if the doom knows what he’s doing. Save fade for when you ult to dodge him stunning you out and otherwise just poke at him a lil bit don’t get too greedy or he will fuck u up

Illari- lastly the new gal. She’s actually super good if you can keep your pylon up. Unless he has empowered punch its really hard to kill illari before she uses her movement ability and her DMG helps a lot when poking a doom before he pushes in. I would recommend not using ult on him solo since he can mostly negate it or just move away before it can be proccd to blow up BUT if he’s already at half it does slow him up a bit when it’s first applied so it can secure the kill

I think I got everyone and gl out there overwatch addicts👍
