for maximum pain, if they did flashbacks to Pandaria bosses, I'd like to have seen: 1) Durumu's maze 2) Elegon's pit 3) Nazgrim and his stance change basically, the 2 big "fuck you, dead if you mess up" mechanics, and the "you NEED to stop attacking the boss or you DIE" one
Legion bosses, Il'gynoth (instant death mechanic AGAIN), Gul'dan (empowered Eye of Gul'dan for lasery death) and Argus (end of the add phase, where you have to find the tree then avoid SO MUCH CRAP)
