With the upcoming changes for DB I think that Evil Hunter (which I mainly use for the Major Savagery buff) is no longer effective for PvE play, and none of the new morphs look promising to me. This means I have a buff/debuff slot available but I'm not sure what to use there.
I'm playing a dual DW setup (one bar AoE, one bar Single Target) with the following buffs/debuffs:
* Relentless Focus
* Power Extraction
* Rending Slashes
I was thinking about Piercing Mark, but I'm getting that debuff from the Night Mother set as well.
So any ideas, tipps, etc would be welcome. Like I said this is for PvE play.
