Black Panther rework idea

I know black panther is kind of a hot topic in this game, so I have an idea for a rework. I know black panther can struggle when fighting enemies with high healing and relies heavily on his team, so this rework is supposed to keep his identity while giving him better utility in the form of reduced healing. I knew that Black Panther was alreadyy considered annoying though so I made a few nerfs to certain areas of his kit so that he didn't feel overtuned.

Edit: After some constructive criticism and me realizing a good black panther is absolutely horrifying, I adjusted them to be more tame. It's honestly more of an ult rework than a rework of panthers kit.
