Nasus is an Assasin building full tank(like Ekko or Fizz). Incoming rework with the other assasin
You cant out run him thanks to is W that he can reapply every time its down(even if you have an escape mechanic), you cant fight him thanks to his Q stack mechanics and is 300 bonus AD on ult. You can't fight him cause he reduce your attack speed by 35%. You can't fight him cause he shreds your armor. You cant camp him cause its a waste of time he's gonna out scale any melee fighter by 15 to 20 minutes into the game. So really unless you pick Renekton I really dont see how your supose to win against him. And i thought Champions where suppose to be fair play but Nasus got nothing fair about him. an Assasin building full tank and still one shot you. Its just strait up toxic gameplay. I really wish Rito would Rework him since he's an old character that uses old season 1 mechanics that are outdated, toxic, and no counterplay to it.
