I’ve found sword/torch to be really strong in a shout/right hand strength build. Use either GS or staff as your off set depending if you’re farming or in a group.
Something like this:

The blinds from GS and teleport and VoJ will keep some vuln stacks on your enemies while constantly applying burning with torch abilities. Plus VoJ resetting per kill is great for farming. With a decently high crit rate you can keep up quite a few stacks of might as well.
