Played a fair amount of crucible and I believe the two one shot abilitys (titan charge and warlock mini nova) should not be one-shots. Shoulder charge should be a move used to confirm a kill on an weakened foe. Not give free kills for just running at people. Mini nova just remove self damage and make its damage comparable to a normal grenade. That way its still a useful ability as the user can still decide between two grenades depending on the situation. I believe these two abilities are way to rewarding for the amount of effort required and should be altered a bit.
