Sure, but there were far better ways to go about doing that that didn’t involve deleting what she was.
I would legitimately be OK with that. In fact I’ve suggested that exact thing. Full revert, make inspire self only, if necessary raise her armor to 100 for a total health pool mirroring Bastion, and push her to the tank category.
I would definitely come back to try that version of Brigitte. If I’m being honest, for overall meta reasons, it would probably better if she was in the tank category anyway.
