Ultraxion Trash
The roleplaying prior to the Ultraxion trash is unfortunately unchanged, but the portion in which you need to kill dragons has been severely sped up! You now only need to kill 5 Twilight Dragons (down from 15) and they spawn much faster. You can watch in the video below (Ultraxion trash starts at 1 minute).
Warmaster Blackhorn Fight
The Warmaster Blackhorn fight is known for being a slog, with you having to go through three waves of dragonriders before the Warmaster himself decides to land to fight. They’ve severely sped up the spawn rate of the dragonrider adds, spawning shortly after the previous wave is killed!
Spine of Deathwing Fight
Infamous ever since it was released all the way back in Cataclysm, Spine is notoriously annoying to solo due to having to manage Hideous Amalgamation adds and their stacks of Absorbed Blood, as you need 9 stacks to trigger a Nuclear Blast (and break off Deathwing’s plate armor to progress the encounter).
With the changes today, 1 stack of Absorbed Blood is enough to send a Hideous Amalgamation add into Nuclear Blast, significantly speeding the fight up!
