Prior to the venth buff it was an even mix between burning wound and darkglare. Now its a combo of all 3 since the venth build can pump on single target fights. I plan on running darkglare for aoe as NF, and then swapping to venth for single target fights. Both use a demonic playstyle which is my favorite anyway.
