I’ve said it in a number of threads already but yeah…
Blizzard seems to have issues with Brig as a support. Simple solution would be to remove armor pack, rebuff some of her shield and shield bash damage, and change her from support to tank.
She can be a brawl tank similar to Rein. She’ll have team sustain through her Inspire instead of a massive shield like Rein, Orisa, and Sigma.
