"We found a bug with Fiddlesticks, so we're disabling him" Meanwhile...
Some of Shaco's bugs:
Two-Shiv fizzles out when it shouldn't when enemies are entering the fog of war (It is thrown, but the spell deals no damage and doesn't go on cooldown)
Clone doesn't work if you're feared while creating the clone
Jack in The Box feared minions sometimes don't go back to fighting and just sit there until they die
Clone's auto-attack stutters and resets the animation if you click R more than once on a target
Boxes can be killed with abilities like Riven's Q once the spell deals enough damage. The box will die without fearing anyone.
Shaco's clone can't attack things like wards or Kalista's ghosts.
Shaco's clone gives Shaco no gold if destroying a Rek'Sai tunnel
Shaco's clone works with the Face of The Mountain line, proccing it and can even give gold and healing to Shaco.
"Shaco is fine and doesn't need any fixes."
