So, just discovered that fleeting expertise is a terrible idea if you're going for a WoF centered build. you might think 'duration doesn't do anything now' but it affects the cost per second multiplier.

so fleeting expertise will give you 160% power effciency, but 40% power duration, which means that the cost per second is increased to 2.5x

I stopped doing numbers there because 60% better energy use is nothing in the face of 150% more cost per second. you're better off with streamline and continuity.
