Can we buff Jhin's mana consumption/lower the cost on some skills?

So I feel that Jhin should have a better mana consumption. Basically after just one W, he's nearly half HP.

The reason I'm bringing this up is because more than likely, he'll be hit with some nerfs, but Riot should compensate those nerfs with buffs for his huge mana issues he has.

Personally I feel he's in a good spot for what he is and what he does, and you can disagree and keep wasting the ban pick on him (if you think he's that OP that he needs to be banned). If you're banning him cause you don't want him in rank, then that's a legit ban, but if no one on the team is picking him, he shouldn't be banned but that's my opinion.

I just think his mana cost on skills could be significantly reduced, especially if he receives nerfs to his damage output or other things.
