I’ve revisited some Heroic bosses lately, after the patch, and it seems that Onyxia, and, most notably, Mi’Da are much more… taciturn right now (previously, I’d noticed differences between Normal and Heroic version of some encounters, namely Majordo Executus and Drek’Thar, in terms of voice lines, which might or might not be related). I wonder if that’s a bug or a feature… Mi’Da in particular was quite infamous for her ‘Echoes of memory… I was strewn across the world… I remember all I have seen.’ — listening to it was, perhaps, the most time-consuming part of the boss fight.
