AD casters shouldn't fall off late game that hard.
outside assassins. which do fall off late game. zed and talon. both do. however not as hard as non-assassin ad casters. i understand why. because you can't burst someone in a full rotation if they are not full squeesh. and not benefit from crit or attack speed. I feel like they need better itemization. ofcourse something other classes can't abuse. by ad caster i mean the likes of renekton. pantheon ( oh pantheon is like the worst champion in the game late game). I understand that AD casters usually have above average early game. but they still need a better mid-late game imo.
