Nasus Jungle (Hear me out)
Before you bash this. Please. Read. Nasus is the champion we all joke about and hate. The fact his Q bop and do more than a 1k true damage smite is annoying as a jungler...Nasus will split push for days and kill you who ever stops him and then base. This is the one thing I don't like about lane Nasus. You have to go triforce for the sheen. Sheen is just really expensive and you have to wait till later for tanky items. Now I took nasus in the jungle.
My experience here was....something else. I got a leash gromp starting E. I then got Q level 2 maxing E all the way until about level 7 or 9. I get my slow at level 4. I get stacks off the Blue sentinel and blue buff, red sentinel and red buff. This gets you a lot of stacks considering you only used q 4 times.
With jungle nasus you aren't at the risk of split pushing and dying since you are some what safe in your jungle. Also with purple smite and blue buff....you will always have mana. You can get purple smite after your first two buffs then power farm into a cinderhulk merc treads. Keep in mind if you get the last hitting down in the jungle with Q....you will be so strong!
I know I'm insane...but I did bring smite tp top against teemo. Just tried to get through lane. Went triforce -> merc treads -> cinderhulk. The purple smite on cinderhulk gave me mana and made me tanky. I know I sound insane but holy hell....it was next level broken.
