Hell yes. Especially consider all the options that could be available in a combination or something like kit: Maybe you could have a single spell series that the 3 spell did a small PBAoE heal for the combo reward. Perhaps another route that gave you some MP back like PLD's lines. Maybe an AoE one could give some damage reduction to everyone in the area of effect or make the mobs do less damage (like reprisal) for 10 seconds. The devs just clearly do not have ANY desire to even think of stuff like this for healers.
