I've only recently started to play Scourge in WvW, and based on all my readings, I opted to go with the Power Scourge build off Metabattle, running Marauder gear, Berserker weapons, Soldiers trinkets with Strength Runes. I'm not in a WvW guild so I mainly pug, but my server has some nice pugmanders and overall it's been really fun.
Now I'm wondering if Celestial wouldn't be a better choice. I know since the Dhummfire nerf, many have said that damage nerf was too much, and that power Scourge is the answer. But I've also read that Scourge is about boon rip/corrupt and barrier, with damage being a secondary responsibility, in which case Celestial makes more sense given you have extra mitigation / defense stats, as well as stronger barrier. Problem is, Celestial Gear is stupid expensive to craft; I have the materials, but I'd rather not waste them if it turns out Celestial is (currently) bad.
So what to do? Help a newb Scourge out please =(
