BP buff ideas

I don't play BP first of all but here are my buff ideas for y'all.

I think BP can be countered easily but can also dominate a lobby, it has a massive skill ceiling which makes a small adjustment just make him maybe overly good.

I think that making it so that if you have a vibranium mark on someone and you have no dash you should be able to use your roll ability and go into the vibranium mark and get a dash and mark the person at the same time. I think that'd give him more damage output as well as much more potential for quicker/multiple kills without making him too broken.

That's my main idea a small idea would be to make him dash not be able to be interrupted by others dashes or atleast make you not lose your dash, for example I think that bucky should interrupt you as well as a thor and magik but you shouldn't lose your dash.

With ult give him maybe 150 extra hp?

These are 3 different buff ideas rather than just one big one.
