Somewhat unrelated, but I'd like to see a type of dummy that could use a weak auto-attack to trigger certain actions or work with certain abilities. I was trying to help a friend with Dark Knight tanking by showing him what I do. At level 60 live targets tend to die too quick (plus it's hard to pull large packs in open world), but dummies don't auto-attack so it's hard to show off how effective Blood Price is.
