Could this work? I posted it in another thread, off-topic really, but I just though of whether the two new professions could actually be combined, so I came up with a shadow-jumpy ritualist type thing...

Grasping Was Kuurong
Channeled Strike (I assume the ashes of Kuurong are an item)
Sprirt Rift
Essence Strike
Ancestor's Rage
Dark Escape
Return
Res Signet

Channeling Magic 13 (12+1 rune)
Shadow Arts 12

Basic idea is pick a target, dash in with Dark Escape, hold up the ashes, open a rift [fight until recharge energy, might need to], channeled strike, drop ashes, return. Ancestor's Rage and Essence Strike are there to finish off if needed or just backup other party members.
I'm not sure on any sort of equipment in factions, but I guess anything that increases energy and/or health/armor would help, seeing as this technique would involve the char getting close to their target
As in the other topic, this could work as an A/Rt, though Kuurong would obviously go
