shaco feedback (remove ap rework ad jg??) long post in depth.
so he has been reworked along with the rest of the assasins for a while now, i think we can safely say the assasin rework was less then ideal for a lot of them, shaco being one of the worse ones.
so let's look at the pros, a lot more of your power is in your passive also clearity on a lot of ablities and quality of life changes as well as AI improvement all nice, cheers riot 
(before i get into the cons i'd like to note ap is the big problem so my stand point on this is from ad jg shaco)
now let's look at the con, ult basically got nerfed mini jacks might as well not exist, jacks don't stack anymore which was unhealthy so this is fine and fair. Q got nerfed, ok well now it's over mana costed utility that's fine, his passive is somewhat toxic i.e look at riven most of the power of a hero shouldn't be crammed into a passive but the actual ablities so you feel like you have impact not just wasting mana and cds. and finally the shiv, o gods what has become the 1 nuke this champ had, base damage went from 50 at rank 1 base dmg scaling to 220 at rank 5, with 100% ad and ap scaling and 10% to i believe 25% scaling slow, new shiv reads, 5 base damage? this is what i couldn't take seriously 5 base dmg when new heros are overloaded with nukes and utlity seriously it's the only damage spell we have. scales to 125base dmg at rank 5 slow got buffed which kinda like but is kinda toxic, so i think having a weak ish slow is probably better for the champ. dmg scales to 125 at rank 5 like really? most ablities have a base dmg over 200+ plus at least 1 decent scaling ad OR ap (not both) and the scaling is pethetic 75% ad and ap with this your shiv is weaker then your auto attacks at all stages of a fight unless the champ you're targeting is less then 300hp so basically dead anyway. also why does every jg need % missing hp get rid of that and give it flat dmg and remove the ap scaling.
tldr (on shaco/ap shaco) in a nutshell everything about new shaco is more consistent but also much weaker teetering on unplayable, however i'll point out ap lane shaco got more toxic and more viable, this just reminds me of ap Yi or Gragas when he got changed from ap mid to tank. the ap style of play on shaco is toxic you play as a poke mage who can't be all in'd on due to boxs, this makes it super bs to play against he pokes n pokes n waits for an all in and you can't counter all in him without feeding kills to boxs, i love ap shaco and pink ward but i think for the health of shaco ap has to die removed and riot focus on making him actually function in the jungle. currently ap shaco is the one keeping his winrate at insane 50-55% ad jg shaco on the other hand is considered a troll pick and sports a sub 50% wr somewhere around 48% or lower i venture (hard to confirm any mass shaco WR stats due to the pool not differentiating between ad and ap. why do i say ad has sub 50%? well the best shacos world right now when played ad have around 50.18% winrate being a challenger player one tricking a hero with only less then 1% Winrate above 50% just no shake my head
closeing thoughts.
shaco went from being secret op to being just ok and then when the scaling nerfs hit shaco become aatrox/eve the walking ward status. you feel like you bust your hump for average results you could easily get with almost any other jungler. but shaco will keep getting hate due to ppl being shallow not learning to counterplay and then looking at his WR and claiming op status, play vs. ap then ad and tell me it isn't worlds apart i think shaco needs to be looked at again but from the stand point of not keeping the duel build/scaling that plus a flexible kit just proves to flexible and toxic to balance.
i look forward to shaco's personal rework that was promised many yrs ago around s3 the mini rework doesn't count as that by the way. even during the assasin rework it was said he will have his own full rework at a later time, meanwhile we're stuck with these changes and honestly if you value your LP just play a diff jungler and this coming from a 600k + mastery point shaco.
so shaco haters rejoyce he's pretty god awful right now, and shaco players don't get down he's still fun bruiser build is decent but that's mostly due to abusing good items any champ not shaco could do the same but it will let you play shaco for now if nothing else enjoy op AP shaco while it lasts
