I agree about the fragility thing. To be honest the easiest way I see to fix it is an enmity boost trait so we can actually fulltime PDT without losing agro to the normal DDs easily. However, I don't see things that do only tp moves (IGs) being relevant in content that RUN seems intended for. As far as I'm aware its intended use is almost exclusive to the new continents as most old content material is random elements and ... Abyssea.
