Honestly I've been wanting them to add EnWater and EnBlizzard. They way I see them is that EnWater is a ogcd buff that adds a dot effect to your weaponskills. Each hit from your weaponskills adds 15s to the dot for a max of 45s. EnBlizzard add an MP refresh buff to your weaponskills. Each hit adds 5s to the buff for a max of 15s.
