Riot, even you guys have to admit shaco isn't in the best of spots

I understand he is hard to buff but you could do something that doesn't make him stronger, but gives him more opportunity to skillfully use his abilities. Things like making his boxes arm in 1-1.5 seconds (2 seconds is eternity in the pace that league has evolved to). Making his clone take turret aggro when ulting after diving. Making his clone appear to take the same amount of damage as Shaco but die at 33%. Making his clone show buffs. Making his ult dodge everything in the game, including DOT ticks, zed mark, tethers.

There are so many things you can do to raise shaco's skillcap without giving him conventional buffs. And tbh this is how shaco should be. His ult should be very good for escaping and dodging. You should be able to trick someone into thinking the clone is real if you do it properly. You should be able to use your boxes without having to wait a year for them to arm.

(don't make his ult take longer though like leblancs passive. That would make it nearly impossible to assasinate people without them just walking away before you appeared.)
