Bag Jesus died for your RNG sins.

That said, as someone who did camp it as a tracker class, you can get unlucky for a couple hours, it happens, but if you go more than an hour without a pop he's probably up somewhere else in the zone. I also got 5'ers here and there. I'd say his chance of pop is more like 25%.

This is all based on experience from someone who took place in the great Shralok market crash of 2015.
