My Wrath is completely unsharded, so my experience using him is limited. But I would say he's designed to be paired with characters that place lots of marks or damage-over-time effects on enemies, since his fury consumes DoT's for extra damage and his basic consumes marks to heal him. Beelzebub and Allied Bomber Boy would be good teammates for him to take advantage of his fury ability. Maybe Rainmaker or Vampire Hunter Eddie to that to take advantage of all the marks Wrath throws around and you've got some great team synergy. Of course, this is purely speculation on my part since I don't have a team even close to this
