No I'm afraid this doesn't work. If only it did (like Shadowpriests can use Dispersion, and Mages Iceblock - and paladins Divine Shield, but they don't have to move anyway), then we wouldn't have to beg for a central spot.

Off the top of my head, it works on Light Vortex/Dark Vortex on Twin Val'kyr and Bellowing Roar on Onyxia 2.0. In ICC, it also negates all damage from Lay Waste in the Valrithia encounter. While it's logical that you can't deter the major AEs on boss encounters, logic isn't always the strong point of how Deterrence interacts with things.

I've never understood why it worked on Light/Dark Vortex since it seems arbitrary to work on it and not on a lot of other AoEs. Since you mention that it works on Lay Waste though, perhaps it works in general on channeled AoEs? Both Light/Dark Vortex and Lay Waste are channeled IIRC. The only other similarly channeled AoEs I can think of that we could test on are a warlock's Hellfire, and Magtheridon's fire thing that needs to be interrupted by cube clickers - I suppose rain of fire/volley/blizzard are also channeled AoEs, but they are also ground targetted, unlike the above.

There's a difference between AE and abilitites that hit everyone. I believe the reason Det blocks Vortex is because it is an ability that hits everyone individually and not a true AE. So while we might have a pretty good idea about whether Deterrence will work or not, we need to test it to be sure.


Do you have a log I can look at that can confirm this and other items that you weren't sure of?

It's possible to avoid Sindragosa's Icy Grip by feigning the moment when you get grip animation. Although, be warned that this seems to randomly break Icy Grip for other raiders as well. Our other ranged would sometimes not get pulled in, but melee still had to run out.
Also if gripped you don't have to wait for the animation to finish and can just disengage mid-flight.

While it is true that Disengage has lent us massive flexibility and mobility during ICC fights, be aware that character movement while Disengaging is still bound by the limited movement coding in WoW, which has led into some interesting bugs in the past. When your character is moving in a limited vertical direction (i.e. jumping, Disengaging, being Deathgripped, etc), the game only records your last position on a horizontal plane, treating it as your current real-time position. A couple situation based from my ICC experience that has led to this conclusion :

- During one Putricide phase 3 fight, I disengaged backwards to avoid an incoming malleable goo. Less than half-a-second before landing, my character died even though I am in the process of landing on a position nowhere close to where the goo is. Combat log revealed that the damage from goo killed me.

- During one BQ air phase, the Incite Fear effect won't break early, and as such I was feared close to another raider, and I promptly disengaged. While landing on an empty safe spot, Bloodbolt's splash hit both of us, causing both of us to die.

Anyone having an issue trying to drop Mystic Buffet stacks on Sindragosa (10) phase 3?
Quite a few times i'm standing out of LoS and still get hit by it (no we're not killing it to fast, getting hit when block is still 'alive')

Quick update on a couple of these:

DT - LM - N - Prevents damage from Coldflame
Yes, actually. Much better-timed log clearly shows Deflects from Coldflame application attempts.

DT - RF - N - Prevents damage from Slime Spray
No.

Is there any special tips or tricks to allow an MM hunter to be able to compete with Surv in Valithria encounter? My performance seemed to take a big hit due to the constant target switching and also movement (to cover both left and right sides of the adds). What made it worse was the fact that I ran OOM a couple times even before reaching the middle of the fight. I finally had to respec to Surv before our successful attempt to down the boss, but would like to try MM for the upcoming weeks.

Also, for hunters, are we going to benefit much from going into the portal room? Our raid's consideration is that healers are going to benefit a lot more, and as such we allowed only healers inside the portal during our last successful attempt.

For Sindragosa, is it true that MM is going to take a larger performance hit compared to Surv? Especially due to :
- Significantly larger number of direct and physical-type attacks (more autoshots from Iaoth, less DoTs, Wild Quiver, etc). As such, has to stop DPS more often due to Permeating Cold debuff stacking
- Movement (during the pull-in)
- Absence of important debuffs (mangle/trauma, sunder) on ice tombs

You should be able to Volley at the 5s mark for Cold debuff to drop off if needed. Its not awesome DPS but its better then the alternative of doing nothing.

If you sit in the middle of the room (Either infront of, behind, or in the boss) You shouldn't have to move much, if at all. Try to stay out of the purple circles on the ground and as mentioned before use viper sting and AotV. I found that ~5-8 seconds in viper put me back up to 3/4 full on mana.
Edit: For my guild atleast, I've also found that on 'downtime' with only abominations up we have more than enough dps to let me switch over to viper as well.
