Unfortunately they gave Judgement a 30 yd range a few xpacs ago and very rarely did I ever have to run in and swing my hammer/sword to regen mana. A true melee healer would need to have either short range targetable spells and good AOE/fire-forget spells or just bash people over the head with a "medical" HAMMAH!!!! or healie bullets. Which personally I would love to have healing like that, would be most excellently hilarious. "Oh, you're hurt? Here let me give you a good whacking to numb the pain!!! Whu, where you going?"
