That. Percentage conversion is basically a percentage penetration on steroids, but nothing really broken:

flat penetration << % penetration << conversion

X% damage converted to is equally powerful as X% penetration against target with no resist at all, but asymptotically increases to 100% penetration the more resist target has:

$$\pagecolor{Black}\color{White}{\rm X% true damage conversion} = \frac{100+{\rm resist}}{\frac{100}{X%}+{\rm resist}} {\rm penetration} $$

So if my math is right, new IE's crits should emulate cca. against squishies but  against  tanks. As squishies tend to fall victims to 2-3 autos anyway, it sounds convenient. New IE should basically be able to free up the slot of pene item.

Also, by removing entirely from the game ADCs are gonna lose one dimension on their damage scaling, putting'em on par with APCs during late game, dimension-wise.
