The problem is the support roster is too small to be worrying about whether or not buffing Brig will make her meta again. Buffing Brig in a way that doesn’t redistribute her kit’s power would be a big problem. Reworking her could turn into a similar disaster. So it’s better to shift where her kit’s power is than it is to continously nerf her, or rework her.
Let’s not forget that we’re only in this situation because pre-rework/post GOATS Brig wouldn’t fit neatly in the 2-2-2 format. At this point, we should be looking at a revert and toning down parts of her kit as required in a way that doesn’t pander to “Supports are supposed to heal, not deal damage!”
Let’s also not forget that those who argue that Brig needs to be more skillful just mean she should have to aim literally everything because aim apparently = skill.
