Hey!
So around half our raid team came back for 8.3, we did the rest of the bosses with significant ease but on this guy, phase 4, we all just start dying and we don't really know why. It might be our raid size (10 man) but I just wanted to make sure there was nothing we're missing. Also, we know about the rogue. He's new and we adopted him.
