Hecarim is actually kind of a monster right now in the jungle.

I know everyone is playing him top for the most part, but honestly after the last changes to him, I think he does much better in the jungle. I never really understood how people did well with him for a while, partly because I followed people's builds and built warrior and a decent amount of damage, but the cinder build, along with triforce is pretty insane. Your clears are amazing, leaving you plenty of time to gank, multiple interupts to stop channeled abilities, ie Kat ult, Malz Ult, Fid drain/ult, ect, who are all popular right now.

Definitely one of my go to junglers right now, along with Voli. If anyone's having issues with him, try the Cinder build, and give it a go. The extra tankiness and AOE for sure helped me.
