Defender Titan isn't much of a healer though, it mostly protects. I think he means we need an out and out class for actually regenerating allies' health quickly and regularly. Borderlands had a character, Mordecai, who sent his super bird flying out and it would steal health from enemies, sending it floating back to him. We could perhaps see a grenade or something similar to a Nova Bomb that seeks enemies, taking their life and returning it to the nearest player. Or even one that simply sends out seekers to the fireteam players, healing them directly.

That's what I was thinking. Armor of Light and what not
