I kinda assumed SCH was going to get a new fairy as well. If Selene heals and hastes, Eos heals and regens.... then "Helios" should protect, sort of work out as a sort of SCH version of Protect/Stoneskin on top of the basic healing.

Of course, WHM would be getting some new abilities, and we will probably be getting into the third healing class by expansion time. SE will balance it out somehow.
