Ooh. I love this game!
Box: Base damage gutted, AP scaling increased, has a shorter duration (active and inactive), and fears Longer.
--- We wanted to reinforce the idea of Shaco boxes scaring the daylights out of people. So we increased the fear duration at the expense of everything else. We also shifted the damage more towards scaling, to help out the late game of AP Shaco.
Shiv: Now scales on AD.
--- We wanted to give a hand to AD Shaco without nerfing AP shaco too much. Since our internal data shows the AP Shaco never bothers with this skill anyways, we decided to shift it a little.
Flash: When ever an enemy gets feared by a Shaco box, the cooldown on this skill is reduced by 1 second.
--- It's important that Shaco be able to maintain his high mobility stealth play. We felt this would encourage strategic use of his boxes while not affecting mobility creep in an way.
Clone: All damage now scales based on Bonus health.
--- We Don't really have a good reason for this, but we thought it would be funny. And at the end of the day, isn't that what Shaco is all about: Getting a good laugh?
Passive: The first time an Enemy see's Shaco, they gain a debuff that Causes Shaco to deal 5-20% bonus damage for 5 seconds. This ability resets after being unseen for 2 minutes.
--- We felt his old passive was too difficult to utilize for people new to Shaco. So instead, we took this opportunity to reinforce the idea of Shaco being gank happy clown.
