jungle went from difficult to walk in the park
Trail blazer and cinderhulk are the main culprits. But trailblazer in particular. The addition to stack on smite is practically like when it had reduced smite cool down.
You could give it spirit elder passive instead: Against monsters, restore 6% of damage dealt as health and 3% as mana. And maybe just 10% extra damage. Or spells and auto deal +10 DMG to jungle. Tbh idk what the solution would be just trying to find answers. Also its ability to clear minion waves makes it very hard to create lane pressure. All the jungler has to do is walk to a lane smite and return to battle. And is really strong at denying enemy of cs (unfreezing a lane etc) after a successful gank. It doesn't reward players for being good at last hitting or making efficient use of spells/autos etc to clear.
It just has so much going for it. Even small things like stunning the scuttle makes it all the more alluring.
