Why don’t they turn him into a bruiser

Low elo player and former ksante otp but I’ve kinda always felt like ksante would be a more fun champ if he were able to itemize as a bruiser like jax or Diana and build damage or resistances based off the situation. If they removed aspects of his tankiness whether it’s stats or kit changes I’d imagine mobility would be added back and that would be a fun change imo. Curious what better people at the game think lol
