I main ADC and I never, ever get % armor reduction items. A tank melts just as fast ( when they're charging towards your team late game) with armor and they have to worry about MR too so no one gets flat out armor.

The only thing that stops a high damage ADC is ninja tabi. But now there's botrk and static shiv, and last whisper doesn't help against that.

And why are you attacking the guy with 400 armor anyways?
