I main hunter. I do think the smoke Is a bit too strong. I got good at sticking people with tripmines so doing the same with smokes is not hard. If I stick someone with smoke he's dead. 3 shots with my AR to finish him. The wombo combo might be even easier because you just throw both nades and walk away because you're getting the kill. Smoke should be nerfed a bit by decreasing the slow effect or the duration of the smoke.
