Rhino rework?

So I know with rhino getting an heirloom soon, which I'm very excited for bc I love rhino, but when it comes to newer frames, he kinda lags behind. I mean roar is his saving grace and iron skin isn't bad but there better overboard frames like dante or styanax. And as for roar it's good for helminth but receives a massive performance to the percentage. I'd like to see his kit slightly reworked to catch back up to the other overguard and dmg boost frames that he kinda fathered in.
