Kael'thas, Malygos, Onyxia, Kil'nara and Mandokir are all faceroll.
Alysrazor 10 normal is okay too, took a few wipes to learn.
Al'akir I couldn't manage, got to 35% but with a little better gear I'm certain it's doable, was doing as bm and just couldn't keep the damage output high enough without healing myself enough.
Soloed FL 25 normal okay but ran into the enrage on XT.
