Played a custom as Pulsefire Ezreal 0/0/0 masteries and empty rune page, took 20+ samples of Q applying damage to caster minions (because melee minions kept taking damage from my own minions), calculated and determined there was no crit on Q so far. I'm bad as far as armor calculations go, so anything beyond the 10 minute mark would throw off whatever Q damage I wanted to apply. Had tier 2 Berzerker Greaves, two Doran's Swords and a Phage.
Also, this does not help. My idea of "standard" is different from your idea of "standard". I've seen multiple people with a "standard AD runepage" containing health quints, flat AD quints, AD/level quints (which is what I have), or even ArPen quints switched with flat AD marks.
