Not sure if this is intended (Shaco's W interaction with runes)

I've been doing some experimentation with Shaco's W with different runes, and while I haven't tested everything yet, I've found the following things:

Scorch - Shaco's W doesn't proc Scorch Cheap Shot - Following the fear from Shaco's box, Cheap Shot doesn't proc on subsequent damage from the box while the Champion is still feared

Again, this may be intended, but if not it'd be nice additional damage - especially as someone who plays Shaco support

edit: same with Arcane Comet
