Sorcerous/Spell Shades bugged?

[Zhalseran]

While not the same thing, something similar happend this thursday. We were grouping up for the start of day2 in Kara, the first pull being the spellshades after Aran. A warrior and I were standing around the corner from them, and one spell shade started waltzing towards us. He was just kinda floating away form the pack towards us. I started running away but the warrior was slow. And the one single spell shade aggrod, warrior ran away and eventually the spell shade went back

Yesterday, on top of a really crappy raid, we had the guests that is wieving the opera visiting us while doing the red hooded bitch.

Later we moved towards the backdoor, and we suddently had what seems like 3 groups of mobs from the balcony i guess.

And then around illhoof we had 2 groups of spellshades and whatnot.
