You can delete Lucio ult with EMP completely or interrupt him during cast
You can interrupt moira ult
You can disable zen ult with ana nade
You can interrupt even ana ult cast =_=
Mercy you can’t stop, but her ult is pretty weak anyway
But brigitte constantly grows armor, and armor is already superior against some heroes, and then it’s also stays on people forever. You can’t stop it and it’s powerful ultimate. That is not how things should work, this needs counterplay.
It counters itself by not being that great of an ultimate
So far in my comp games it seems as if all focus goes to her if she ults mid fight is the only counter. Most Brig Ult Plays are used where an enemy can’t see such as before the fight so there is no counter play to that besides a brig ult yourself Im pretty sure
Just kill brig as fast as you can, a decent junkrat makes a brigette regret everything.
You focus her down, surround her with a barrier, lock her off from her team.
D.Va Bomb and Rip Tire kill through it.
Basically, like Molten Core the only way to stop it is to kill Brigitte.
Doing the most basic thing. Dealing damage.
Pokes, burst damage, or focus fire her during teamfights when she has it with her.
Like basic damage? Something that all characters offer? It also doesn’t get healed by healing so it’s not really that hard to beat.
Usually calls for a burst ulti, either pulse bombing brigete, or I use my soldier ulti or dragon blade to either get rid of the armor or kill at least 1 person.
You shouldn’t be allowed to have an opinion…
As an avid Mei lover I came to inform you that Blizzard shafts her and her entire team even with her ult 
Haha good joke 
it makes her unkillable,and gives her team a great advantage.
It’s overall a pretty underwhelming ultimate as far as support ults go. It stacks very slowly and has a fairly low cap. It’s best feature is allowing Brigitte to move full speed while holding her shield.
In any case, Riptiring it is a great counter-ult since it’s going to be up pretty much every time Rally is up.
If you don’t have Junkrat, then just standard focus fire on the target you want to kill. If it’s used before a fight, it’s only marginally better than a toeb armor kit on each hero. If it’s used during a fight, proper focus fire isn’t even going to notice it due to how slowly it stacks, until you’ve already killed off a player or two and have a number advantage, at which point it doesn’t matter.
And of course killing Brigitte herself simply ends it, though doesn’t delete the armor already in existence.
not just that a zen with discord orb and a d.va i know this becuase i killed brigitte last night either during or just right after her ult after a teammate zen thrown a discord orb
It already has counterplay. Literally just pick Junk and blow her up, she can’t handle that damage with ult or not. And for a support ultimate it isn’t even that great, it’s similar to Mercy’s ultimate where it’s kinda useless VS other ultimates but extremely strong against a team without ultimates due to the protection they provide.
Riptire counters it…
It’s pretty powerful despite some of the messages here. Focus fire Brig and burst damage is the only real answer.
I can tell you this, the armor keeps stacking even after taking a Rein-Hammer Down. Tried it not 2 long ago, She ulted and I got HER ENTIRE TEAM in it. No idea what my idiot team was doing but there was no were near enough damage to secure kills and they ended up winning that team fight T-T
At least I got to pin the Mercy after my Ult
its 6 v 6 not 1 v 1…
Any form of burst damage can punch right through her armor 
Toss a Junkrat nade, Pharah rocket, or a D.va bomb into there.
Or, you can use a sniper to peel off a character’s armor in an instant
I don’t know why people say it lasts forever. Literally do 100 armour damage and it’s gone, it really lasts no time at all.
