Champions move swap.
Does ever thought "Wow this move would suit (Champion) more"?
For me it would be
W
Q should swap.
SO that Kog maw would have a Aoe long range barrage of spit then swapping him out would change it to the attack speed version?
And JINX would have the W so that her mini gun would feel more like a mini gun, and her passive with it would make it feel more natural.
Post ones that you feel like it would be better. (You may alter the move slightly to feel more natural)
Devour would be much better on
