You know they added AD to the Vamp Scepter so that they could increase the cost and removed straight-up LS from Doran's Blade so that you couldn't start with LS, right?

That aside...

If a carry has enough LS to completely nullify your poke, you're either poking wrong or you totally screwed up earlier in the game and let the ADC get fed.

You complained about LS 'snowballing' on ADCs, when it's not really the LS itself snowballing, it's the carries themselves, and you know... THAT'S KINDA THE POINT OF ADCS. An ADC that doesn't snowball is kinda useless.

HOWEVER: I will concede that having reduced effectiveness for LS on Ranged Attacks (or alternatively increased for melee) is an interesting concept, since item-based slows already are reduced on ranged...
