And? Rabadons doesn't effect AP champ's autoattacks. My point is such a system would either have to have an arbitrary cap (Which would mean crit's current problem of difficulty in itemization is still in effect) or would be excessively powerful as people build up 150% bonus damage on-hit by stacking IEs and dealing upwards of 2k damage PER HIT.

A damage amp effect should not be able to stack. Contrary to popular belief, AD carries don't NEED crit chance. The only reason they NEED it right now is because there are no high AD/AS items in the game. You want AA reliant champs to be a threat late-game without making AD casters excessively power? Give them an item that grants 60 AD and 40% bonus AS. AA reliant champs are dealing more damage with such an item than AD casters, and you don't have to resort to an excessively complex and archaic system to do it. Ta dah.
