I'm engaged on a discussion with another bard on reddit right now and the difference between perma WM and only Opener Barrage WM on a 2:40 min dummy fight i parsed was by 2 dps, with WM coming on top.

In a real scenario, we won't be able to stand still for that long and need to move out of the way a lot more often by making the Barrage EA then autos the more reliable rotation, in my opinion.

Still, WM isn't what developers advertised to us: the standard stance to use to maximize dps to drop only when there is high movement to do.... or maybe it is, since most of the fights required me to move out of the way every 10-20 seconds <.<
