Sorry if it's not a good English but here are my personnal thoughts about How Shaco changes would have been 10 TIMES better (what i written in an other post):
"There was so many things to do with this Shaco Rework to put him at the same level than all the other assassin as new Rengar, new KahZix or new Talon... and a less risky pick:
Passiv:
10% - 30% damage from behind, same passiv than before (30% was before the 20% we have now), but it scale with levels. So it's a nerf in Early and a up in Late Game.
Q Spell:
Reduce the invisibility time at level 1 (but less than what they did) et up it at level 5. Early nerf / Late Game up. Give a reset to his Q, when we kill or assist, a total reset OR a CD reduction: ex: 12sec CD if kill/assist= -6sec on Q spell before the CDR application.
W:
Make boxes invincible when we put them on the ground, before they go invisible. No need to up their HP and so on... only so the ennemi see the box but that a random AOE can't destroy it immediately or a single AA....
E:
Keep the same stats than before, but ADD +% missing HP. So Shaco is better in the Tanky Meta (meta that will stay tanky when we see the new Tank masteries, letality that is a nerf of armor penetration to make snowball less important) and eventually nerf slightly the damage at level 1 but keep the same amount than it was at level 5.
R:
Make the Clone less stupid, just as Tibber that becomes a monster when Annie dies. Instead of putin 3 boxes on the ground that a ridiculous and useless cause they have the same HP bar and can be OS.... when the Clone die he should make damage AND an AREA FEAR just as the boxes (W)."
Please don't forget that since Shaco was released in LoL, he only had NERFS again and again, the only up he ever had was gain more HP / level.... even the meta changes, jungle changes, items changes are nerfs in majority for him.
About that Assassin Update:
Akali feels really bad, how the hell can she put 2 AA to get her burst on a single target... except if the guy is AFK it's impossible, so she became useless.
Zed... well i guess he's kind of "ok" but changes were useless.
Ekko, Tank Ekko still op, AP Ekko ok, don't understand his changes at all.
LB, i think it's one of the worst... SUPER EASY to play vs her, if she touch you with a spell run back and gj wp & dodge her CC or she OS you.
Talon, i think his E is OP as fuck, especially cause of the 2sec CD... they nerfed Shaco Q range (cause it was more than a flash) and now they give Talon a sort of ininit flash when there are some walls...
KahZix, WTF, he was allready good before the update, now he became OP, ulti going on when he is in a bush, 1.5sec invisibility + move speed bonus out of a bush (REALLY??? he can go from a side bush to the middle of mid lane while invisible, even wards can't detect him while invisible...) He's really OP, but if he fails to attack an isolated target he's fucked.
Rengar, well he's good now, going for a one target OS to a multiple target OS, only thing is that it's hard to play him right now, much more than before and i think it's good like that. Before an ADC could litteraly not do a single thing before dying, now the support can take the Rengar Ult on him and they can counter him. (let's be honnest Rengar before rework was op vs squishies, now he's balanced)
Katarina, well need LOT MORE skill to played. Tried her and that gameplay feels AWESOME!!! Before she was braindead (jump in ult and gg wp or dead), now her gameplay is really interesting and she isn't useless or weak at all!
Shaco... weaker assassin of the game early. His mid and late were a bit buffed, but in comparaison to other assassin update he really need something more. Wrote what i had to said about my thoughts about how changes would have been done. But the new jungle is a MEGA nerf for him, not able to clean golem & wraiths (except if you like gangbang), not able to cheese anymore. New items aren't that good on him, letality and so on... they were designed for champs like KahZix & Talon more than for an assassin that relly heavily on AA.
Overall the assassin update is good, less braindead 0.5s OS, being able to outplay the assassins like LB or Rengar, don't understand the KahZix changes they are really overpowered (someone is playing KahZix for sure in dev team lol). Let's see what will change until the start of Season 7, but as my main is Shaco and he's the only char that still make me play this game... I really hope they'll make some changes for him, especially with the maths on his abilities.
