So I've jungled Nocturne and Nunu as well as Xin, but I'm tempted to try jungle Panth.
His passive would work well in the jungle allowing him to take less damage.
His "E" would allow him to crit all the monsters below 15% health, improving his clear times.
His ganks would be scary, especially after getting his ult, with proper warding his counter-jungling would be amazing.
He has no sustain.
He has to have blue or he can get oom extremelly quick.
He excels at laning.
Doesn't take advantage of his great early game.
Sounds like fun, might have to test it out....What are your thoughts?
