If one sorc is topping damage and healing in the WF, it generally is showing two things--1) I think the sorc/sage class is a touch stronger as a class at this level, especially in the resources department. 2) More importantly, even with a good toon, people that can do this are often quite talented at the game.
Additionally, you might just be focus healing a bit too much to only be doing 40-50k a WF. Especially being 31, with access to Surgical Probes. He might be around his allies more and thus having more damage to heal, while you focus on 1-2 guys doing the objective.
