For as many problems as Shaco causes, Riot doesn't seem to be in any hurry to rework him
Can't buff him because his winrate shoots up to 56%+ within a few days, then he inevitably gets nerfed in the very next patch. His kit is obviously problematic, but Riot seems content to sweep him under the rug until they randomly remember he exists and throw him a bone, whereupon the aforementioned pattern takes place.
No one in the community talks about him either because 90% of the boards would be happier if Shaco stayed a shit champion forever, so any attempts at constructive discussion about him are immediately swamped by downvotes, or ignored outright. It's getting really hard to stay interested in the game when the only champion I truly enjoy playing is treated with such disdain.

smoke screen would have been soo cool on shaco for a large AoE ult.
and twinking of the ADC class to burst per second.
