Which champs do people suggest buffs/nerfs for, but you think are fine?

Hear me out now. I know I'm just a lowly unranked plebeian, but I honestly believe Kha'Zix is one of those champs that doesn't need anything right now. His last set of buffs really put him in a good spot and if I kite my camps right I can even come out of jungle with near full hp at level 3 and a pot while laners are at level 2 and possibly 1. Not to mention I can still heal off and take scuttles if I need to top off. Kha'Zix is a champ that takes a lot of quick decision making to do really well with. Each of his evolved abilities are all in really good spots now. Massive increase in damage on his Q, his W provides vision and a 50% slow, E is explanatory, and his ult is still good despite what people may try make it out to be. It's still increased movespeed and longer invisibility. This ability alone when I evolved it has saved my life more times than I can count when something like a Morg snare hits me and I can just be untargetable when the enemy doesn't have a pink ward to place.

Kha'Zix is just right for me. He isn't too strong and he isn't too weak. His weaknesses and strengths are clearly defined. Such as not going to far from your team. You just left yourself open for Kha'Zix to leap on you and probably gave him the reset to catch a target who already left the fight on low hp. But good coordination works against Kha'Zix and forces him to play passively for the game since all of his damage comes from isolation.

I wanna hear any champs you guys have these ideas on or if you have anything you'd have to say about Kha'Zix. I can honestly expect downvotes. It's not often I get to talk about champs with others and being unranked there probably are loads of people that know better than I do.
