Been away so long I want to go revisit some of the content I haven't seen in a long time or maybe missed.

Any tips on the ideal way to spec/glyph for this? Or is it somewhat fight specific?

I might end up doing this on my DK instead but I thought I'd explore how viable it is. I don't quite understand this Demon Hunting glyph and how that whole concept works, or if that's even relevant to soloing old content.
