Remember how for most of Season 4 Shaco's Q made the turrets switch aggro away from him

even while Shaco attacked a champion while remaining in range? No? Well that's ok most people forget he even exists, especially Riot apparently. Also, remember how 6 patches ago you suddenly weren't able to cast summoner spells while he started his E wind up for whatever reason? No? Well it's because he is a buggy mess but Riot completely forgot about him.

Aside from general bug fixes he desperately needs some power shifting and QoL buffs, but Riot seems too busy ruining Skarner again.

Some very small proposed changes:

1. Make his W aggro whoever you are auto attacking (Similar to the way Hiemer's turrets are).
2. Make his E's blind apply every 5 auto attacks instead of it being RNG based.
3. Remove the E passive slow from his auto attacks and make his E's Active slow longer, far more potent, and a decaying slow as opposed to a perma-slow.
4. Make his ult explode when you die instead of just having do nothing and then explode in the middle of no where after it stood there or walked around aimlessly for a bit.
5. When his ult snaps back to him after leaving its leash range, make it leave behind the same puff of smoke as his Q.
6. Just fix all of his stupid little bugs like how if his ult runs into a minion it'll stop trying to go where it was going and it'll just stand there. Or how if an enemy pings you before you ult then the ping will stay on you and they will immediately know which is which. It's seriously infuriating.

I am currently making up his entire "Champion Update" and will post it soon.

All in all if Shaco gets at least the changes posted above I wouldn't care if goes untouched for another few years, he hasn't had any meaningful changes since he got nerfed in the beginning of Season 3.
