Nasus deserves a 50 range buff on his wither
Nasus is a fairly problematic champion because of his juggernaut nature combined with his infinite scaling. I do acknowledge that the simplicity of his kit is difficult to balance Riot and that he´s one of those champs that get problematic through numbers, but the nerf on his W was the overkill.
600 Range is the Autoattack range of Ashe, Caitlyn Tristana , Jinx,Kogmaw and twich have all acces to higher autoattack range than his wither has. Furthermore the existance of QSS and Banshees make his task of debuffing AS reliant champions even harder.
ADC´s that do not have the range to abuse him by outranging him have other tools to deal with him (outside of getting peeled). Ezrael has high ranged poke,Sivir has her spellshield and a kit inbuid movement speed steroid. Vayne can ltierally outduell him in a 1vs1 by just pressing E and waiting out the duration of his wither. Also multiple indirect changes (like items he likes or the jungle changes) made him weaker than before Riot had buffed him inthe past. A 50 range buff would still remain him in a nerfed stage because of all the indirect nerfs and changes to the game but at least not force him to flash when he wants to wither a Caitlyn or a Tristana.
