Hunter have insta kill knives if u r skilled. Goldwn gun insta kill from far away. Arc blade doesnt need even more def, speed is more than enough to dodge anything. They turn invisible, backstab is insta kill. Trip mine is insta kill to 1 or more enemies if u r skilled. They have the highest agi from all 3. They have mobile supers. They r very focused on PvP I dont see why do you say they r underpowered. Hunters play very different from titans or locks. A lock can get close and sponge some dmg thanks to overshields, but, its slow as a turtle good luck trying to flee. Titans r melee beasts their fist of panic is strong aoe but it can be easily dodged shoulder charge as well. Good luck trying to run away from arc blade or golden gun. If you dont hear them activating them u r good as dead.
