I'm not allowing graves into a game with me until he isn't obscene
Seriously, there's no way anyone playtested this and thought it was balanced.
"Hey guys, you know how adcs are the gods of free (as in no cost no cooldown) sustained damage, as well as being the best at taking towers, with their trade-off being that they're squishy, usually have little burst, and can't 1v1 unless very far ahead?"
"Yeah, that seems fair even if it means that the whole game is played around them."
"Yeah well we're reworking one so that he not only retains all those strengths but also has none of those weaknesses!"
"Rito pls"
