RUN has much better VE/CE values for its spells/abilities. If you're looking to fulltime your pdt set and have a substantial amount of enmity there's really not a lot of options for RUN at the moment. You can however macro in a decent amount of enmity for you're spells and abilities. the mythic for one thing has 18 enmity. the JSE GS has 10 which has become the staple of the RUN arsenal. You can get the Eihwaz Ring, Trux Earring, and Invidia Torque for a combined enmity of +15. You might want to macro in the neck though and have twilight torque equipped. You can also use Earthcry Mantle and Goading belt for another +10enmity. All in all that's and increase in 35-43 enmity and you can get more through ammo and the hands you mentioned.

I know you're thinking that's not enough compared to pld consider this even if a pld were to have +100enmity his ma/ja's still wouldn't be producing as much VE/CE that run can generate innately. With the mythic, run is going to be an absolute beast in terms of tank potential and a competent DD to some degree which is way more then you can say for pld even with a mythic.
