My party has just disbanded after hours of fighting the Dwayna. This encounter is broken: Dwayna randomly stealths what gives no chance to take her down in phase 2, sparks lose aggro randomly (happened few times), hitboxes of circles are way too small. The only chance to kill her, is to bring full exotic/ascended glass cannons and even with this, it is not certain to take her down. You still need lot of luck to not get trapped, in one of broken mechanics. And as reminder, any other path in any other dungeon can be completed without bringing glass cannons to nuke bosses, only this one require it. You said, your goal in Guild Wars 2 dungeons, is to make them more fun to play, this encounter is not even close to be “fun”. So, my ask is: nerf Dwayna hard or redesign whole fight. I enjoy hard bosses like Giganticus Lupicus, but I can’t stand encounter which don’t reward you a kill, even if you did evrything correctly.
