Maybe, but he is so easily kited and even with his 45% attack speed slow adc's still manage to blow him up anyway
Hes utter garbage in lategame like pretty much any tank is since they blow up just as fast as squishies except nasus lacks the hard cc other tanks have
He will not be dealing any sort of damage vs anyone diagnosed brain dead and those ranked above since even brain dead autistic monkeys are capable of kiting an immobile melee champion, especially due to mobility creep in items no nasus damage wotn do much for him lategame neither will his tank stats they become irrelevant lategame
All he has lategame is his E and his slow, which ofc gets cleansed, so pretty much his e is all he will have i lategame
Earlygame he is utterly shite and can't do anything vs most champions unless he maxes E and avoids stacking
Midgame is usually where a stacking nasus can shine but this only works if you don't fall too far behind in lane and if your team doesn't buckle under the pressure from you pretty much being afk for 20 minutes before becoming useful.
And due to last seasons and this seasons changes snowballing goes 15 times faster so you can bet your arse that afk farming for 20 minutes is a guaranteed loss.
So the only option for nasus is to put out a lot of earlygame pressure by maxing E to bully his opponent out of lane and draw attention top
this way you are actually usefull for the first 20ish minutes after which you become a peel bot for the adc
rather then being useless till minute 20 then from 20-25 mins is your moment of power after which ur useless again
