Conqueror Change

So this might be a silly idea

(Try not to remove this post like you did my last one, mods. I saw that.)

But what if Conqueror was changed from stacking 8% true damage, to 8-10% armour penetration instead?

You'd have the power to have a go at punching through tanks/bruisers, but it wouldn't exactly shred every other class of champion out there.

What does everyone think?

(Yes,give me more downvotes)
