I was in a group for vet WGT when we got to said boss, which I had never done before. Even being a magicka templar with plenty of range, I couldn't keep up with the billion portals popping up and my group was quickly dying. In about three runs, I had portals four times while one of our dps got it once, the tank got it about three times and the other dps maybe two or three. One of the dps chewed me out a bit and now I'm trying to figure out what to do when I get portals again.
I am always in third person, so if I back up too much my camera will leave some blind spots. If I'm in the middle, it's super easy to miss portals. If I go into first person, I'll get smacked by everything in sight. Not to mention we'll be relying in the tank's off-healing when portals go off on me. Again.
I tried watching some videos, but it doesn't help when the group positively melts the boss (deltia) and you don't really get to see how they deal with mechanics, especially a healer.
I tried using Radiant Oppression, which I found too slow and I was forced to run around, killing my stamina fast (which the dps also yelled at me for). Vampire's Bane was a little more successful, I think, but I didn't really get to test it too much since everyone's favorite dps quit.
So how am I supposed to destroy portals fast enough, let alone even see them? They always seem to pop up BEHIND a player, so I miss them until they start pouring out dremora. The (rest) of the group is experienced, but even they can't really afford a boss, billion ads and no designated healer, because they're running around flailing at daedric portals. I've tried planting myself against a wall, but they always pop up on the other side of the room and not being a stamina build I can only run so much. Any ideas?
