Hunter: Phoenix Rising. Summons a solar Phoenix that hunts down two enemies, causing them to explode on death. (Yes, Borderlands inspired. Sue me). Can be upgraded to kill up to 4 enemies. Can also provide shield buffs to teammates via Blazing Morale. Titan: Vindicator's Might. Draws forth a Lance made of Arc energy. Can be thrown for precision / AOE damage, or be swung. Has a short to mild timer. Can be upgraded for farther throwing distance, and chain lightning. Precision damage can over-penetrate, hitting up to 2 targets. Slows movement speed comparable to wielding a heavy. Warlock: Supernova. Taunts all enemies within X yards to attack the Warlock. Warlock absorbs 75% of damage for Y seconds, until exploding, killing all nearby enemies, and him/herself. Can be upgraded for farther taunt distance, more absorption (up to 90%), or longer duration / explosion radius. (solar)
