How to fix pyke from being a unkillable stealth tank when hes supposed to be an assassin

hello league boards, im back with another installment of challenger jungler predicts how the game will be fixed and offers riot some advice on how to fix problematic champs or items in their game. You may have seen a previous post about how to fix adc itemization months prior to the changes ( https://pastebin.com/c0E1bABq )

Pyke , he's supposed to be an assassin support but is just played as an unkillable tank who is perma-stealthed and heals to full whenever hes poked or escapes a catch out. if riot accepts this as a problem, as he is very low interaction to play against as a full tank, similar to season 6 ekko and fizz,

the fix is to have his passive healing scale off of AD rather than as a base value.

seeing as how hes comically squishy when NOT built as a tank, consider AD (and consequently HP due to his passive scaling) be able to give him grey health greater than his set max hp akin to overheal. this is one way to add power to his assassin build without buffing already solid base numbers to encourage a higher risk, higher reward build path. The overheal grey health mechanic isnt as integral a change as heal scaling with ad, but just an idea to add power back to a kit that would likely be significantly hamstrung as a result of this scaling change.
