I like this idea, but I don't really know where to start with it beyond gimmicky groups--like let's put a single, naked asura in the middle of a field with 20 deadeyes lurking about. Hilarity ensues as small groups get excited about ganking an easy kill.
Did you already have some ideas in mind while posting this, @Hrom? Maybe I'd have more helpful ideas with a narrower focus, like "How do we counter X" or "How do we make something that does Y"
