I think every class should have close range, long range, and support so here goes. Arc Warlock: Lightning gauntlets, or orbs that orbit guardian damaging close enemies. Void hunter: Void wall that absorbs damage, or the ability to "phase" into a different dimension to avoid damage and revive. Solar Titan: Pluck a small comet out of space and smash a random, or specific area. Think Warsaw with less damage.
