very obviously a rhetorical question.
best shield in the game without question, incredible damage potential, hardlight damage instead of kinetic so hard counters d.va, insane ult, aoe doomfist punch.
2 days in and i already want to uninstall this game again
Cat ultimate seems to be the most reliable. 
Rush her. She has no mobility and only little means of shield recovery.
Dominas weakness is any kind of tank with fast movements or brawl potential. She can do nothing against DF, Ball, Winston and kind of struggles also against Mauga and Queen. Currently she seems strong, because Domina vs Domina is a neutral matchup like Rein vs Rein is. As soon as other tanks are getting played it will get obvious. No idea if Dva or Orisa will be good or bad against her or neutral. So far I would say neutral.
As for DPS anything with a lot of movement or a lot of range is annoying to deal with for her. She herself has no mobility and while her range is good, she lacks burst damage outside of short or midrage with her prism. Same goes for supports. She is quite good against the cat if you can aim, but cats ult will kill her 99% of the time.
Reinhardt. Especially if those fools are also running Emre. Rarely do I say that Reinhardt is powerful, but against this nonsense? Yeah. Reinhardt is pretty crazy. Until they remember you are Reinhardt and swap.
In most cases? A team of Supports that refuse to heal against focus-fire.
Or just refuse to heal their team, period.
But basically, Dominaâs main weaknesses are as listed by the previous posters. Rush her down, isolate her. She can actually be out-poked by the enemy team, she lacks lethality (most tanks do against healing), Getting around her barrier and sheâll crumble pretty easily. Weak to flanking, high healing/mitigation.
Uncoordinated teams will also struggle to do much of anything with her. Panopticon sets up a lot, but can be easily countered by just about anything, especially if the team refuses to follow-up or doesnât know how.
Hanzo.
He breaks the shield quickly and has high burst. He breaks her economy, worst case for the CEO
The same as sigma they are weak to being ran over by brawl tanks and since her shield is a cd instead of resource once itâs placed if you get it past it she gets nuked.
I would assume junk does a decent job at getting her shield down because of splash. Youâd then be useless against everyone else but ayâŠ
Shes a poke tank, she is not good into brawl.
Literally she ruins the whole update, seeing that cringe shield every game
ok, very clearly forgot that 5v5 exists. i only play 6v6, and she is the strongest tank that has ever existed. a lot of the ârun her downâ type comments just dont work with an offtank
lmao have fun with Sigma +Domina
Ram is really good since he can not only punch through the shield, but he breaks big sections of it as well with his punch, as well as being able to sustain with block, slows her down with vortex, and he has longer poke. He also has stalwart, making pushing him back not very helpful. Winston is really good as well, especially with his new perk.
Yeah, so long as you can dodge the e and donât get wall slammed she has almost no sustain.
The primary is dangerous but the beam gives advance warning that you can use to dodge the shot. Altogether, anything with mobility seems to work pretty well into her.
In my experience so far it works in 6v6 as well because both teams get an off-tank.
Honestly, I think Sigma is better than her in most regards. She can shoot down fliers, but apart from that, heâs got her beat.
Her weakness is in her knockback.
You dive her when she doesnât have that.
She is melt.
Or something bursty that can just go over her shields. Like some sort of explosive rat or something.
im not saying that i cant win against her, its just that she is so incredibly strong, that i am no longer having fun.
Iâd say that depends on the situation. The fact you can poke holes in it relatively quickly and once itâs deployed you can go past it (and itâs got a timer) make for some weaknesses you can exploit.
She really is vulnerable to diving though. In a vacuum 1v2ing other players yeah.. sheâs good, but if youâre gonna handwave away with âexcept I play 6v6 and none of that worksâ I gotta ask what your offtank is doing⊠or your team.
Sheâll probably get toned down cause all released heroes do, but for all the games Iâve played sheâs definitely not invincible.
This. Walk past her barrier.
