Currently relics are auto-passed even if you could use it in one of your offspec weapons. I'm not sure if there is a better way than defining what each class can use. If there is not, maybe this saves you some research: https://github.com/mlsen/raidcomp/blob/master/frontend/app/scripts/misc/wow.js#L236 (created for a different project).

Also thanks, appreciate your hard work on this!

I used the same approach in every other aspect of autopassing.
This will definitely make it a lot easier to implement, thanks a lot!

Just a heads up (not sure if it's relevant for you) but Blizzard classifies Storm relics as being of type "Wind".

Why have consistent naming anyways.. Not important in my case, but still thanks!
