A fun build exploring the options you can have with the changes to 2handers. This build makes use of tempest rush with tailwind to fly through the map mowing down anything that gets in your way.

Key points for this build:
You must have a weapon with high spirit per second and make use of all the skills with spirit per second. Just ignore normal mobs and breeze by them, only stopping to kill elites. Use serenity and seven sided strike liberally as your defenses are quite low since this build requires taking spirit passives over defensive passives. I could only get this to work in Act 1 because Act 2+ mobs just hit too hard, but I imagine with better gear this build could be used very effectively in Act 2+ to just blaze around looking for all the elites.
