Halfus Wyrmbreaker HC - Disc Priests

[Vordie]

Hello there, writting from my iPhone so please ignore any typing mistakes.

I'm my guilds main Disc priest but we run this boss with 3 discs on heroic 25-man. I was wondering what you and your guild will do now that we will only get the buff once we kill a dragon. We go for Whelps -> Time Warden -> Nether Scion and I was wondering if the buff will be applied once you kill one whelp or all of em.

I am guessing most of you actually run with at least one disc priest. So, thoughts?

Edit: By the way, my question is for all raiders/raid leaders, not just priests.

Time Warden > Whelps > Storm Rider > Nether Scion > Slate

Whelps will be harder to kill now since the most AoE came from the mages Impacting Halfus.

Disc will be useful when you kill the 2nd or 3rd drake
