When do early game champions actually fall off?

{quoted}

All I see is them beign strong start to finish, only beaten by being outscaled if someone survives early game? wtf

Stop being ambiguous. Which champions are you complaining about? Use an example.

early game is lvls 1-7 mid from 8-13 late from 13-18

look at QWER how many of these does your champ need to max in order to be a champion? if 0, then early game if 1, then mid game if 2, then late game

oh right should actually answer teh thredd

early game falls off when mid game ends so when the map hit's lvl 13 you should have outscaled whatever early game champs there are unless they're like 2 levels ahead already or something.
