@ Riot : Shaco Rework
I hear Shaco's rework has been shelved, due to identity issues. As a former Diamond Shaco, I love the champion but feel like he is in the dust of this quickly growing game. He is great early, but often seen as toxic. He is very susceptible to counterplay, and falls off drastically, forcing the team to play around your gimmicks. Unless your team properly exploits your snowballing, it's difficult to have a carrying impact, even if you are far ahead in gold and skill level. Why not toy with the mechanics of his kit to give him more leveled consistency throughout matches, and maybe even get him some competitive limelight? Rather than alter him, I feel you could just tweak mechanics, such as:
- Changing damage types, to give more diversity to his burst. His Deceive could be amped damage rather than crit, and his other moves could have phys. damage.
- Add new effects, to give him more tactical uses. This could be anywhere from adding an effect to Deceive's smoke, to adding multiple clones to Hallucinate.
- Have the moves affect eachother through passives. For example, one idea would be lowering Deceive's cooldown each time you throw a Shiv at someone.
And for those AP Shaco fans, maybe even have the AP scaling alongside the AD scaling rather than in place of it. Whether it's through hybrid options, or through a character-specific item like Viktor has, I don't see why these two playstyles can't be individualized.
I have seen other good ideas posted on this board too. We're all ready for some Shaco love. 
P.S. I spent a bit too much time theorycrafting, and made a list of ideas here: http://boards.na.leagueoflegends.com/en/c/gameplay-balance/9NintKhh-more-shaco-rework-ideas
