Currently Jack feels sub-par to other trappers. With the new trapper passive that is a few hundred times more effective than his own, simply without the damage, he doesn’t feel like a viable pick in my opinion.
He needs a new special ability I believe, this one doesn’t do much anymore. Even before, it was weak when compared to the others; as it was too slow. But the damage bonus in domes made it helpful.
Just giving feedback on his current status from a monsters perspective.
