Given it could be a possibility... as there 3 elemental types, one per class. I'd guess some sort of hybrid role, as each class is currently offensive or defesive/support. (Unless you're a hunter, you just kill stuff before it kills you.) Also warlocks are masters of the arcane arts, weird they can't use arc. Warlock - Arc Grenade types: Pulse, Arcbolt, or Flux. Jump: Glide + Speed, speed + control, or Blink. Super: Tesla's Ring (AOE): Pulse (large stationary), Arcbolt (multiple jumps), or Super Storm (increased range). Melee: Spark: Discharge, Over Charged (increased damage for slightly higher CD), Static (holds the enemy in place for a moment) Titans - Sun Grenade Types: Solar, Fusion, and Swarm. (Maybe Incendiary instead of solar, as Titans have more conventional methods.) Jump: Lift: Height, Control, and catapult. (very standard on titans) Super: Trail Blazer, leave a fiery path with buff to abilities (melee CDR, like sunsinger's grenades): Increased resistance, increases movement, or intense heat (increased damage to fire trail). Melee: Ignite: Flame Shield, Brimstone, or Circle of Life (increased duration to Trail Blazer). Hunters - Void Grenade Types: Magnetic, Scatter grenades, and Axion Bolt. Jump: Double Jump: Height, Triple, or Blink. Super: This is tough, I'd say something stealth based, and again highly offensive. Maybe something similar Nova Bomb, but with a rocket launcher, or something involving throwing knives. Melee: Blink Strike/Energy Drain Combo: Backstab, Surge, or Lifesteal. Hunter with void is possible the hardest to create something around and it not be a super assassin.
