So devs decided to not nerf the tracer and d.va and add a counter for them instead. the counter was brigitte. they gave her armor to counter their bullets , stun to counter their mobility , shield and burst heal to counter their burst damage and cc to peel them off their allies. this caused a massive powercreep.
No imagine if they want to do the same for brigitte and instead of nerfing her they add a counter for her. they should create a character who ignore armor and shields , has long range to avoid taking damage from brigitte , be immume to cc to make brigitte abilities pointless and has infinite damage.
