I very much agree with making some big changes to Repair Pack. I personally think that the ability in its current form is one of Brig’s biggest problems right now. For one thing, its range is way too long. It feels really out-of-place in relation to her overall design, but somehow everything else has been trying to balance around it, instead of the other way around.
I even sat down recently and tried to figure out how to address as many of the ability’s problems as I could think of, coming up with a rough idea of a rework: My take on a Brigitte (Repair Pack) rework idea
