I personally like playing Brig when I can, but usually it’s either abolute carry or getting 0 value.
before anything it’s important to remember you’re talking about a giant hit box and her shield is only 200hp.
so the 1st tip is focused more on composition.
always run a shield with her. either Rein or Orisa+sigma.
Brig’s shield is weak and can not really protect her wall. the shield’s job is to block either burst damage like a D.va bomb or a rip tire. or let her have as a small healing time bonus (more on that in tip #3).
You would usually want to run her with teams that either need a close range cover or brawley teams that can use more damage that goes past shields.
While the most famous combo for a Bastion comp is a Baptiste-Mercy one. if the enemies run a dive and or your 2nd dps is a long range one, Brigitte will usually be a better option than mercy in order to bring the close range cover.
The 2nd tip is countering . because of her big size and close range she can’t do much in the long range, heroes like junkrat,Widow & Pharah will melt you, so never play her against them, not only you"ll die fast but you also don’t get your passive which will result in low healing as well.
The place where you do want to play her is against close composition with spam damage. with dive being the most obvious one.
Heres like Reaper & Tracer are super weak to stuns and armor and playing Brig against them can make a huge difference.
The 3rd tip is remembering you’re a support before anything. you have a lot of armor sure, but your damage is low and her self healing is low but active over time.
you want to stay close to your tank and help them deal with enemies- if your below full hp try going for a hit, and then immidiatly block with your shield for a second before doing so again, that way you’re using the shield to gain more health, healing your team and keeping yourself alive.
4th tip is about her ultimate. While the ultimate can be used offensivly to make sure your team has an advantage, you can also play it in a more deffensive playstyle against some of the more spammy ultimates, against ultimate abillities like Soldiers,Ashe’s, Meis,Hanzo & hog.
5th tip is playing agressive vs playing deffensive. Brig’s value comes from getting close since only then she can get her healing only by close range fight, but at the same time just like previous tip says she can be extremley vurnable.
her shield bush can be used to block enemies but it can also be used to escape and gain a distance between enemies.
her whipe shot at well, can be used to chaise down flankers but can also create distant for escape.
It really deppends on the enemy and yourself, if your hp is high and the enemy is alone feel free to play a little bit more agressive. but if you’re fighting an enemy like Reinhardt or having low health it’s usually just safer to use the abillities to escape.
I Really hope these tips will help
