Can you restrict ADC from stacking these items?

This would solve a lot of issues with ADC this season, since the standard build for most adcs require at least two of these in their build.

So you would rather them either a) deal no damage as they wouldn't have strong enough crit multiplier (if stats stay the same), b) be able to grab defensive items without sacrificing other core build items (if damage is buffed to compensate) or c) revert back to lethality builds where only like 4 ADCs were even viable?
I mean, if you're limiting items for classes, then mages should only be able to get one MPen item, tanks one health item, and assassins one lethality item.

Many adc's main builds are two of them. If you just had Shiv+RFC I'd agree, but you're wrong otherwise.
Have no idea why this is being downvoted
No one even buys all of those 4 times all together, they make a choice of 2 between the 4.

Either
or
but no one is stopping anyone to mix it up a little but in doing so it will cost you the damage you are going to be doing, since you wouldn't have any AD just pure attack speed, which would be useless on most ADC's that don't benefit from attack speed.
If you want to mix things up a little then, they should be only be able to acquire one. ADCs deals too much damage, restricting this will solve that problem.
If this change would go through then other champion roles would replace them as this would just make them utterly useless.
