I don’t think the heavy handed approach to nerfing Brig is necessary. If you want to balance her for top tier play, just take away the armor from that repair pack for full hp heros.
The shield nerf is absolutely going to make her unplayable in the any rank. Makes her squishy and totally defeats the philosophy behind Brig being the protector and peels in the backlines.
She already has very little mobility compared to plenty of other heros. But to nerf her to this extend, with the rework to her shield? May as well just delete her off the game. She is played to bring some sort of agency to the support players, to sort of make her counter play against one shot characters like genji and df. Making her downtime increase and such? She is not viable at any given rank at all.
If you guys want to nerf brig to this extend, may as well just delete the character. Don’t even bother with her.
