I got to go with solar, even though I use voidwalker. Ex1: Defender puts up a bubble, Striker destroys bubble, Sunbreaker destroys Defender and Striker. Ex2: Golden Gun vs Arc Blade, more than likely Gunslingers are to far away for a closeup fight, same can be said for Nightstalker vs Bladedancer, if a Nightstalker and Gunslinger traded shots and missed twice (Nightstalker perk) the Gunslinger will still have one shot left. I can't accurately say how a Warlock battle will play out because I would be bias to Voidwalkers and Stormcallers.
