Small change to Shaco boxes suggestion.
I've all ways wondered why when Shaco's boxes fear someone, they don't have some kind of sound effect like a laugh or anything. They laugh when you place them which makes absolutely no sense.
Boxes are all ready annoying so imagine very nearly getting a kill and then BOOM, you detonate a Shaco box and it's laughing at you as you're helplessly feared. That just would play so well into Shaco's character as a trickster.
It's the little things like this that can make a huge difference in having fun with a champion.
