Yes! Yes we do need more ways for him to farm b/c he has received so many soft nerfs over the course of this season that he needs help where ever he can. Thematically it doesn't really make sense that he can stack a Shaco box or Teemo mushroom but not a GP barrel.
I am truly sorry if any of you are low silver or bronze but the truth is Nasus is not OP in anyway shape or form and has to work 5-10 times harder to be relevant than almost any other champion in the game. Just because he has a passive play style that doesn't fit the cookie cutter trade game of 98% of every other champion of the game doesn't make him OP it means you don't want to adapt. If he's hugging turret and the wave is pushed gank mid or tp bot for a play and grab dragon. If his Jungler is camping you then tell your team to wreck bot or mid and push for an early drag. Learn to control the wave so he is susceptible to being ganked by your jungler. Play a ranged poke champ and deny him farm. So yes he does have a lot of counter play.
Nasus has more abused weaknesses than almost any other champion in the game. All of his primary build items have been nerfed, FH, SV, IBG and TF. Teleport was nerfed twice this season, he got no love in the juggernaut update while Garen and Darius were given better team fight and defensive steroids when they already had decent stats in both.
So asking for a minor streamline in the thematically logistic department isn't really asking too much.
can stack nearly everything in the game with his Q that is on the map and/or produced by enemy champions. There are TWO enemy objects Nasus cannot stack: GP barrels and Inhibitors.
barrels since the champion was reworked.
being is able to jump out of bushes with his passive, except if a person playing 
puts a stealth ward in the bush he is in.
