plz rework nasus

1 single persone shouldnt be able to carry the hole game alone even if they are fed. i mean look at other roles. an assassin cant strait out 1v5 with out out playing them massivly. lets say katarina she has to not get hit by a single stun to be able to 1v5 but nasus? nah he can get hit every single spell in the game and still kill everyone in your team. he has no skill shots he has a perma slow. he has extra 900 hp and 55 mr and armor. how the hell am i supposed to out play that? u might say well dont let him farm. how am i supposed to not let him farm if he isnt even taht weak early game(am not saying his strong or anything he just doesnt have weak enought early game). and there is no way u can change him with out making him tottaly useless so plz just rework him
