Oh! I have a story.
About 3 weeks ago I got Cape Westwind while I was leveling my last two tanks. As soon as the barrier dropped I rushed in to MT him facing him so he's pointed up the hill. For some reason the DRG in our party decided to stand just behind me. Turns out the boss has a cleave. And said DRG had paper for armour. And died. This all went down before the adds spawned.
So. Then the adds. Instead of everyone just zerging the boss so the adds all rush in and picked up by a single tank AoE the entire group but me proceeds to single target down the adds. And not even in a coordinated way. Everyone just went ham on a random add and since everyone was spread out all over the place it was kind of chaos. Combined with the boss using his massive AoE at least twice this resulted in 3 more deaths by the end of the fight somehow, and the second set of adds actually spawning. Which of course the entire group proceeded to take down with single target abilities in exactly the same haphazard way as the first.
I was just there at the top of the hill the entire time with the boss with my mouth agape wondering if what the heck I was watching was real or not.
