Both Auspice and Boost- spells should be kept up 100% of the time if the WHM can afford the MP and the risk of running into melee. The Subtle Blow effects from Auspice and Boost-AGI are mind blowing. People are always fighting for 1 more point of stat to be squeezed out. A WHM can give 7~ if they're not lazy. SCH's merit Stormsurge just to gain the same effect. Whether or not a SCH will give you a Storm is a different matter entirely.
