You literally made me login to comment on this... I will say that I really like this build, especially late game. Unless you can get a hard leash for your entire jungle, sustain pretty much sucks, but once you get your stacks going and cinderhulk built, it's pretty much GG from there. I usually main fiddle as my jungle, but I just put up an amazing game using this build. The only worry is what to do if you get invaded at beginning of the game, you dont really do damage to stop anything from happening. Overall, I will say that if you're a guy who's tryna bring Nasus jungle back, this build is worth. Probably would switch to Tracker's knife though.

may i ask why not the mastery that increases the duration of the neutral buff?
