Why doesn't Riot try to create Assassin Items for "melee only"?
Problem with Lethality items at the beginning of the Season was in my opinion that certain ADC's (Jhin,Varus) abused these lethality Items which completely blocked off bot lane diversity. Why wouldn't Riot consider making "melee only" items? (Crit problem in Season 6. could've prevented certain things as well)
are all ranged assassins. That's why.
