Anet is clearly working toward the standardization of their skill type. They gave a skill type to almost every single healing and elite skill in the game with the exceptions of Shelter, Mending and Ether Feast. All specialisation gain one skill type for all their utilities/healing/elite and more and more skill type are recycled to allow more synergy with runes and trait across all profession.
With all that in mind, it make sense for Anet to fill all the skill type without any Healing and Elite skills. I doudt they will do that for the expansion, but it’s fun to imagine what kind of skill they could add. Here a list of several option. I intentionally left those skill without any numbers in term of duration, cd, etc. Because a discussion about balance could take forever.
