All he does now is pick people off.
They have tried to keep his AP scalings and his AD scalings so there is some diversity in his builds, but all it really does was force him to stack artificial damage sources just to keep up.
If he builds AP, his clear time is fucked because he has 0 AoE and 0 sustain.
If he builds AD, his passive is wasted, his boxes are worthless, his Q is worse than ever before and his ult relies on the auto attack alone. His CC is frontloaded because if he tries placing a box in combat, the opponent takes a step to the left and avoids the entirety of the skill.
If you watch any Shaco player, you'll see that they almost always save their ult as an iframe, rather than a source of damage... because the damage is appalling.
His crit passive now scales off AP, two usually polar items, leading to a gold waste, not to mention if he builds crit and he gets a regular non passive crit, it overrides the damage from the passive and only adds 40% AP to the attack.
His Q is purely mobility, no damage, also gives a huge warning when used from fog/bushes, unlike his counterpart assassins. They did the same with LeBlanc, making her Distortion(W) focused on mobility rather than damage, yet it still has some.
Also worth noting that his Q and passive no longer apply Luden's Echoes, making his opening damage so much lower.
His W doesn't prioritize champions, and can be seen/heard through fog of war, not to mention dies in a whole two hits!
- Zyra's take plenty more than that, Heimers scale with his AP and his level.
- It also has a damage modifier on it, limiting to a maximum of 3 attacks to kill it. This makes the armor pretty worthless.
- Shaco's usually die before they enter stealth, making them the #1 way in League of Legends to waste 50 mana, because unlike the other two, it takes just over 2 seconds to deal damage.
- They are also vulnerable to sweeper, unlike the others.
- Does not apply spell effects, unlike the others.
Anyone with half a brain just lets minions take aggro and just laughs at it.
Why does Shaco get the raw deal? They changed it in his mini rework to add extended time based on his AP? What kind of slap in the face bullshit is that? The only time the boxes are relevant is early game, when he has low AP anyway. Even with a full build of AP, you'll get an extra 30 seconds duration?
His E does fuck all damage until the target is on low health, because they killed the base damage, then the scaling damage, then made the execute damage scale with level, (again a double standard since Elise and Lee Sin get the full % missing hp from level 1.)
His R explosion range is so fucking small (250) you have to be doing the wrong thing to be hit and then have to be doubly retarded and walk back into the mini-boxes, assuming the enemy jungler hasn't just smote one of them.
He used to be rewarded for forcing or baiting good fights and punished for picking poor ones. Now all his damage is towards the end of the fight, which is good... granted he lives long enough to get them that low. Escpecially with things like Bloodthirster and Death's dance adding artificial health to his desired targets, making his execute damage lower.
He was finally in a decent place and they over-nerfed him back to the realm of Urgot. There is a reason he never sees pro-play. The proof of the pudding is in the playing.
