DH runes and Deadly trapper?
Currently using in my power build using Staff and p/p. It has great synergy and allows you to load up a whole lot of might to prepare for an unload or vault. Shadowtrap will get you 21 stacks right off so if you set this right on top the guy dodge back or some such then use the trigger to get that might you can hit him hard.
I found that due to the ferocity from the runes I could also take IP over unrelenting assault as this can really start getting some nice incoming heals. That said you can skip the CS line entirely and not suffer too much by it and take trickery or acro. 15 percent more damage from lead attacks on a vault as you loaded with might stacks hurts.
A great food to go with this is the one that gives 20 percent boon duration along with might on crit with no cooldown. That 20 percent allows youat least another attack or two under full might before the stacks start falling off.
This kind of synergy was the first thing I thought of when I saw Runes of the Dragonhunter. There’s a lot of potential there.
