According to the healing blog it's the same order: "Fortunately, the order in which the Paragons join the battle is pre-determined, despite what the dungeon journal may say, so you only need to learn one sequence of Klaxxi abilities to be able to complete the fight."
Guess we'll find out.
If people don't have time to read the entire guide just learn these abilities:
Be ready to form a line from the boss to the targetted player. Also don't stand within 5 yd of each other while in the line.
Watch big yellow puddles on the ground.
Red, Yellow, Blue Toxin
Spread out if you have red, spread out if you have yellow, stack up with 1 other player.
Ignore the Bloods if the boss is low enough. (20% or so). They can be stunned and slowed but not rooted.
Rik’kal the Dissector should be nuked down asap to avoid Parasites. Pretty sure we can do that without heroism. Parasites are a major pain so we might wanna use CD's to nuke Rik'kal.
We should consider using Heroism for Incase In Amber mechanic.
