Guild Wars 2

The problem with this build in WvW is that you’re basically playing a glassy melee build that kills slowly. You’re trying to go all-in on Dhuumfire by taking Reaper’s Onslaught, but not only is this a sustained DPS loss in comparison to Deathly Chill, but you’re forcing yourself to want to spend most of your time auto attacking while in Shroud. In general, Dhuumfire does less for you than simply scepter auto-ing, and forces you to suboptimally use Shroud. Most individuals in WvW can simply kite and out-range a build like this.

If nothing else, I would at least recommend swapping Reaper’s Onslaught for Deathly Chill. In general, though, a number of other things could change to become more optimal, such as swapping Rending Shroud for Chill of Death, and potentially swapping Decimate Defenses for Chilling Victory for increased overall damage and sustain.
