Would such build work?
Because of the way AH works, I wouldn’t recommend it for duels because it’s not as reliable as a solo sustain option. Theoretically the build would be good for group play, but PoV is pretty lackluster on its own as a form of condition removal, so you’d likely run into a bit of trouble with conditions. Also, as with any guardian build, you’d likely run into trouble getting kited by classes with higher mobility, even WITH swiftness.
