New Animations on Certain Classic Legendaries
I've only seen it a couple, didn't get the chance to record it and haven't seen much about it on the subreddit, but I noticed Ysera and Onyxia both have new entrance animations, I wonder if all the dragon aspects have gotten this treatment.

There are new ones for Ysera and Onyxia, and for Malygos, as colossus_geopas mentioned . Our artist Dominic did them!:)
