Hunters I would agree maybe be underpowered but they aren't the worst, golden gun if your halfway decent at aiming can be used so many way for pvp like taking out ppl who just got heavy or just going on a rampage, and the throwing knife used with the perk that allows it to burn let's u reload when facing an enemy that regens Health or their sheild, blade dancers can go invisible to escape a mob and regen health, or when u blade dance you use to to slash away or go crazy with mass killing. There isn't a worst class, some may be more over powered or underpowered, but it all depends on how you use them
