Nexus Princess Ky'veza Abilities
Similar to the old Netharion's Lair "Shell Game" Weakaura, this Weakaura was used to not have to pay attention to the intermission at all. Once the swapping was done, the Weakaura would just tell you which one to click. This has now been hotfixed, but the Author has mentioned on the Weakaura page that they are looking for another way to determine this.
Blizzard is clearly trying to stay on top of this and making sure that Nexus Princess Ky'veza on ?? difficulty stays as true to the intent as possible.
