No, d20 states that LoH is a standard action, and that it can be used on Self or Party Members, which is why I think they went a different route with WoB.
But I agree, the description of WoB according to d20 makes it sound more like a clicky skill much like LoH, which can be used a set number of times per rest. Maybe a combination LoH and a Divine Healing type of buff? It should remain Self Only though.Lay on Hands (Su)
Beginning at 2nd level, a paladin with a Charisma score of 12 or higher can heal wounds (her own or those of others) by touch. Each day she can heal a total number of hit points of damage equal to her paladin level × her Charisma bonus. A paladin may choose to divide her healing among multiple recipients, and she doesn’t have to use it all at once. Using lay on hands is a standard action.
