I know how to buff Jhin

So currently Jhin is a weak pick and I can tell you the reason why. Jhin has incredibly high damage against targets that are low. The fourth shot of auto attacks an deal over 1000 damage and the fourth shot of his ult can deal close to 2000 damage. But there lies the issue: why are you wasting around 2k damage on a 500 health target?

S here's my proposal: instead of dealing increased damage based n missing health, Jhin should deal increased damage based on how much health they have. This Jhin is dealing 2k damage to 2k health targets instead of wasting it on someone who is going to die anyway. Thoughts?
