Should Shaco's Two-Shiv Poison vs Monsters be changed?

Shaco's still got some RNG in his kit via Two-Shiv Poison, which causes jungle monsters he attacks to have a 20-30% chance to miss with their attacks. I feel that should be made into something more consistent, but I'm sure people don't want to give the clown any sort of buffs.

I hate Shaco, but I also hate RNG in this game. In the case of crits, it CAN make for more interesting plays (though not necessarily in a fun way), but in Shaco's case it doesn't really feel fun, just awkward.

Shaco's currently not on the Champion Rework list, and he might not be competitively picked often (he's VERY RARELY picked), but would this be an acceptable way to give him a mini-buff?
