I agree with a healer class, however it can not be a "increase health regen" type(atleast not all of it) due to how destiny handles it. If you increased the regen of a player, but that player was taking damage, you have wasted abilites doing nothing as they will not heal, it needs to be a health restore. I would play this class as a main, there is only so much that can be done with the current system needing to back out of the fight to heal. ~idea~ Keep the solar grenade but twist it, friendlies restore x amount of hp while standing inside of it.
