Smiteless jungle warwick

I just played my first ranked game against a warwick in the Jungle. The thing is, I couldn't tell he was jungle because no one on their team had smite. He ran and , so I figured he'd be top lane. "Oh cool," I thought. "Two jungles to farm, ez freelo." I was wrong; so, so wrong. After stealing his first red camp and fb'ing their actual top laner Ekko, I figured that would set him back a bit. I was wrong. After building and alone, he snowballed incredibly quickly. Clearing out both his jungle and mine effortlessly even without smite. He ended the game with the most kills, least deaths, most damage dealt, most damage taken, most damage healed, and most gold earned. Without smite. I just don't understand why riot would acknowledge the fact that jungle sustain is too high and rework a 450 ip jungler to have enough built-in sustain to pull off a smiteless jungle while being down one of his first buffs. Whatever, at least I know that he's deserving of his permaban state.
