Baseball Jayce
I think jayce's ult
does the process of changing from pitcher to batter in baseball. When he uses his E in melee mode it could show he hit a home run. Also when you use your Q it could be like a normal pitch and when you use your E to boost your Q it would make your ball travel like a fast ball. I don't know, that is all i came up with so far, but add anything you think the other skills could be like.
