I recently tried a game playing as a physical DPS Evelynn Jungler. My build was something like
Cloth Armor+5 Hpots
And I forget the rest. Smite and Rally and Hate Spike first made getting the golem at LV 1 a breeze. Late game I was able to actually push, and do decently in team fights because of having 200 attack, 1.9 attack speed with M/S, a high damage hatespike, and the madreds effect.
Even though Evelynn's moves aren't fit for jungling, she doesn't lane very well, and is more fit for roaming around anyway. Hate Spike and Smite make her a usable jungler. She's useless laning, so why not do this?
