Questions about Shaco Rework

Hello everybody. I do not own a PBE account and was not able to find out the answer regarding 2 Questions i have about the Shaco rework. So hopefully a PBE tester or a Rioter can answer them for me.

First one does the Passive Crit Dmg Scale with IE 50% dmg increase and Crit chance the way Ashe Passive does?

If you build Crit on Shaco and you do a Backstab and you role a normal Crit will you do the normal Crit damage, the passive Critdamage or whichever is more if the Passive Scales?

Okay now about the Q Ability.

NEW: 20/35/50/65/80 (+100% total AD)(+50% AP)

[NOTE: This damage is multipled by the passive's mini crit! - src]

If you Backstab and do a Normal Crit, in case it gets ovewritten will the Q Ability use that Damage Multiplier instead of the Passive one?

If you Q and hit from the front and crit will the extra damage from Q crit or will it be something like your Base AD crits and you Do the 80 Flat extra. Seeing as there is no real AD Scaling to this Ability which makes that part with 100% total AD redundant.

Ah well these are the Questions i have hopefully someone can answer them.

Basically what it boils down to is if you go Crit Shaco can your passive actually lower your Dmg especially if it does not Scale like Ashe Passive and even if it does Scale there can be Scenarios where it could lower your Dmg depending on how the Passive Interacts with Crits and How Q interacts with Passive Crits and Normal Crits.
