I hadn't changed any graphics settings, but like I said maybe my view was further out. It was just really strange though, the fight seemed so much less chaotic, I was able to see where the worm was headed, mostly avoid the dust, stop and kill some adds. Something just clicked I guess, I was like, "huh, why exactly was I wiping so much to this fight..." (hadn't leveled or gotten new gear either).

Perhaps the "running around and screaming like a little girl with no rhyme or reason", isn't a strat I should adopt for other fights when trying to figure them out hehe.
