Ok
As a Shaco main, with a PBE account, I have come to the conclusion that this is OP as duck. Just look at that scaling! There is no way that Riot is going to let this go live, either that or this is a devious attempt to make Shaco seem so strong that they make it seem justified to nerf him into the ground.
My opinion as an ex Shaco main:
You are just not used to Shaco being strong. Shaco has one of the (damage wise) weakest kits in the entire game. He is very item dependent.
The Q buff won't change anything in the early game because it scales with BONUS AD. He will be stronger in the mid/lategame and he really needs this buff because right now he is trash compared to other assassin junglers.
The 80% scaling looks pretty crazy at first view but if you look at it closely you'll see it won't be that crazy.
Let's compare the Shaco Q with the Rengar Q (both champs have the same job to do, bursting the carries)
Shaco: The damage is : 20 / 30 / 40 / 50 / 60 + 80% BONUS AD
Rengar: The damage is: 30 / 60 / 90 / 120 / 150 (+ 0 / 5 / 10 / 15 / 20% AD)
Empowered Rengar: The damage is: 30-240 (+1.3 Total AD)
--> Rengar's Q deals A LOT more damage in the early game. (As it should be because Shaco's Q is also an invisible cap closer)
Let's compare them at level 10 (with 1 full item (Duskblade)) Duskblade Stats: +55 attack damage +10% cooldown reduction + 18 lethality
Shaco: The damage is : 60 + 44 (80% * 55 AD) = 104 Rengar: The damage is: 150 + 20.4 (20% *(65 Base damage of Rengar + 37 (3 AD * 9 lvl up))) = 170.4 Empowered Rengar: The damage is: 160 + 30.6 (30% * (65 Base damage of Rengar+ 37 (3 AD * 9 lvl up))) = 190.6 --> Rengar's Q still deals A LOT more damage
Let's compare them at level 18 with full build: Boots, Duskblade, IE, Youmuus, Guardian Angel, Death's Dance. This makes a total of 300 AD (55 + 70 +55 + 40 + 80)
Shaco: The damage is : 60 + 240 (80% * 300 AD) = 300 Rengar: The damage is: 150 + 43.6 (20% *(65 Base damage of Rengar + 153 (3 AD * 17 lvl up))) = 193.6 Empowered Rengar: The damage is: 240 + 65.4 (30% * (65 Base damage of Rengar + 153 (3 AD * 17 lvl up))) = 305.4 --> Shaco deals more dmg than the normal Rengar Q but still less than the empowered Q at full build! Don't forget that Rengar can instantly recast his Q after he used the empowered one.
Short summary:
Q buffs won't change anything in the early game. He will still not be able to fight the enemy junglers. He will get a slightly better midgame and a stronger lategame. His snoballing potential will definitely increase.
Your opinion is a joke, that's my opinion about your opinion.
Playing in pbe is nothing, you can take the games in pbe as normal games, you will se when shaco comes to live, he is not fucking op as you think he will
