They need to change it. Solar Ability kills on Gunslinger is pulling teeth. The Throwing Knife doesn't count, yet Blink Strike (Bladedancer), and Smoke Bomb (Nightstalker) count as their respective elements. They need to change it to where the Burning Knife counts. Giving an Advantage is BS. Sunsingers can do Grenades & Horseshoes Bounty is less than 5 minutes. Titans can do Arc Ability Kills via Shoulder Tackle. Gunslinger Hunters need a bone... Tripmines suck, Throwing Knives suck, Ability Mods (Scavenger, Keyhole, Gunslinger's Trance) suck compared to Bladedancer & Nightstalker Ability Mods.
