Wukong and Master Yi should use energy.

Alright, I feel like this would work since, even though they aren't ninjas, they use Wuju, and have the whole Ionia home place, so it makes sense.(Lee Sin uses energy, so don't throw a "they're not ninjas" reason at me."

Wukong is very combo heavy, so sfter a few spells, he would be a lot weaker until he can regen some. Maybe give him a bit more damage to balance that. He could get some energy back for each champ he hits with e. Also, if he kills a minion with w(since it's not easy to do), he could get some energy back.

And for Mazter Yi, it would be good, since his resets wouldn't be as annoying. He wouldn't just be able to spam Q. He would probably get energy back from his oassive double hit, and for when his Q hits a champ.

That's just my thought. Any one else agree.
