Shaco late game

so shaco's power was supposed to be moved from early game beast to having more late game power. however it feels like they missed the mark on shaco late game

so here is my 1 idea to make his late game better with keeping his 'counter' of red trinket and control wards still the bets way to counter it

let shaco's W have charges based on R rank

example, new passive on R

-shaco now can hold onto 2/3/4 charges of his W with a 11/8/7 (scales with CDR) second CD on cast but the recharge is still based on the W CD

this makes his W more like himer turrets but still keeps its CD long enough that he wont get it off multiple times in quick fights BUT he will be able to set traps better without so much wait time, while at the same time his boxes are still very counter able by control wards and red trinkets, this increases his strength while maintaining his weakness being his counter to boxes

however his boxes duration on W no longer increases by AP, this makes him still able to set up a good number of boxes late game with less set up time, but also keeps him from having to many out at once
