Riot claims to have increased the power of Shaco's passive

So, Shrive (a Rioter) has posted in the PBE the following regarding Shaco's changes: http://boards.pbe.leagueoflegends.com/en/c/champions-gameplay-feedback/auEY7jEU-assassins-mini-updates-discussion

>Early game abuse reduced, tricks increased while providing more playmaking and teamfighting options in the late game Backstab (Passive) has a cooldown, but provides a greater effect Shaco's Deceive (Q) duration starts small and scales with rank Shaco can place Jack in the Boxes (W) while Invisible, briefly revealing him

But there is one thing that is not true.

>Backstab (Passive) has a cooldown, but provides a greater effect

Considering the context of Shaco changes, the new passive does not even comes close to being stronger. Do the math. It's weaker.

Q+Passive

At base AD (117):

NEW: Q: 80 base + 99,5 = 179,5 With Passive: 260,3 With IE crit multiplier: 350

LIVE: Q: 117 * 2,2 = 257 With Passive: 308,8 With IE crit multiplier: 379,8

At 300 AD (117 base + 183 bonus):

NEW: Q: 80 base + 255 = 335 With Passive: 485,75 With IE crit multiplier: 653,3

LIVE: Q: 300 * 2,2 = 660 With Passive: 792 With IE crit multiplier: 972

Damage in previous combos:

NEW: Damage: 120 * 1,45 = 174 With IE crit multiplier: 234

LIVE: Damage: 120 * 2,2 = 264 With IE crit multiplier: 324

TOTAL DAMAGE OF Q+P+SS:

At base AD:

NEW: 434

LIVE: 572

Witt more AD, the difference becomes even bigger.
