One of the things you can do is the striking dummy that is released for each extreme and savage. If you unlock Stone, Sky, Sea at Idyllshire then you can unlock the version in Radz-at-Han as well and it is available at Palaka's Stand. It's not going to tell you if your DPS is great, but if you beat it, then there probably isn't a major problem with your rotation or your gear. The more time remaining when you beat it, the better.
