Nerf AD Shaco, shift AP power: Change execute to 40% bonus from 50%, Add 10% AP ratio to his passive
I feel like the nerf to his clone explosion damage/radius and box duration hurt AP Shaco way more than AD.
Yes it has the potential to deal as much or potentially more but the conditions for that are hardly available and most times the clone pops out of range of the intended target, especially with much more time standing still after auto attacking without bonus attack speed which is much more available and viable for AD Shaco.
I know my fellow Shaco mains will hate me for saying this but his Shiv execute damage is a bit overpowered for both playstyles, so shaving it down to 40% bonus from 50% would IMO be the perfect trade to allow 10% AP ratio on his passive(sorry AD Shacos)
The nerf to the execute is also a tiny nerf to Shacos first clear which is needed, but as he builds more AP it increases his clear.
so for example, with runes and first item complete he'll have around 80-90 AP, his autos deal an extra 8-9 damage from behind, seems very reasonable to me with the execute nerf. Given the fact it's physical damage, it's scaling will reasonably negligible.
