Back when they gave Brig the nerf hammer in May 2018, Geoff Goodman said this:
However, this is exactly what you’ve done now. You’ve overnerfed Brigitte. Stripped her of her sturdy, melee, armour-wielding healer identity and you haven’t made any changes to make her better.
You’ve reduced her to a backline, repair-pack spamming heal bot and you’ve left her there. Orisa has recieved multiple buffs since she became a throw pick but you’ve made no changes to Brigitte.
