Blade Dancer counters Gunslinger : Slam a tripmine grenade down in front of you and start shooting them. Blade Dancer : Post Mortem, Arc Bolt / Flux Grenade and Blink Strike simultaneously Defender : Magnetic Grenade and Shotgun, stick them and ready your weapon. Striker : Fist of Havoc or Post Mortem with Lightning Grenade on the ground and Storm Fist Voidwalker : Nova Bomb or Axion Bolt and Lifesteal Melee. Sunsinger : Fusion Grenade (or 2) + Scorch or Revive and get payback. Those are the best options I can think of and do on spur
