Unless your the only healer in a tank group, why would you need all those heals? I used to be like you, a " Healer Druid" but I find the Druid role has changed vastly over all these years. Our DPS contributes more to the raid then our healing does. If your in a caster group with people who know how to play then you only need to load 2 heals. Between those 2 heals and your AA heals you should be able to keep your group up.
