Been doing WvW with septer/warhorn and its does pretty well imo. I have as much healing as possible and run travelers runes for the mobility. The 3-4-5 heal seems to really help if I pop them all right as we push thru a jungle of necro death circles. I could be wrong though, it just seems to be my favorite healer class. The celestial gear gives me some damage and toughness as well so I can help dps and don't die if someone sneezes on me.
