Buff Shaco to put him on par with other assassins!
Currently assassin like
etc. have ways to jump in on the carry and get out before they can take much retaliation. Zed has his shadows kata resets leblanc a million blinks and so on.
When you go in with Shaco you have to hope you can outplay the enemy with your clone, which might I add is already clunky to move and doesn't like to listen to you as well as can easily be differentiated due to auras/items/damage taken etc.
I don't want him overbuffed or anything because a good shaco can be a nightmare, but the amount of work/planning and timing you have to put into shaco is far greater than any other assassin in the game. It's highly unfair that Zed can dive into the entire enemy team and blow up the carry then get out for no cost at all while Shaco has to outplay someone. Not to mention vision changes make it really easy to shut him down. Let's also not forget his immense lack of waveclear without tiamat.
And that's just ad shaco i'm talking about. AP shaco was already hit hard with the removal of DFG. Ludens was alright but now they're nerfing ludens echo which makes it even harder to play him. AP shaco won't be building tiamat so he lacks waveclear crazy bad.
His only reliable source of damage is his E while the damage is good it's easy to simply build banshee/mr in general and completely counter it. His W and R are good for damage but it's crazy hard to use. Especially since, unlike Teemo's shrooms for w/e reason his boxes are able to be damaged by anything upon setting.
With the introduction of the new jungle and cinderhulk it's already really hard for him to manage a consistent effect over the game because counter jungling isn't that good now. His mana cost never really go away as ad shaco and are terribly bad early on for ap shaco.
I'm not going to say he's bad but compared to energy/no resources/low mana cost spammy assassins now a days that have 5 million ways to get in and out easily he's just so outclassed. I love the clown but he needs some love from Riot
