Highest dpm method for aran?

Finishers feel way to slow to be worth using. I barely ever use tempest, fenrir, or judgment except when I'm just about to run out of combo with no monsters in range to hit, and barrier isn't very useful and is just a hindrance to using drain. Maybe if you have a 4-5+ monsters at the same spot and continuously rolling spin and judgment them, but I'm still doubtful.
