Ignore this WIP please it will probably change, so whilst this comment is here please just move along

NOt phased yet ...

1) What we did that made a world of difference was had all the healers add "Dark Barrage" to Grid to see who's getting the debuff. It's under Status->Auras->Add new Debuff or something like that. That way you see immediately who has the debuff and toss heals. If you get on top of it immediately, it's absolutely no problem to heal through with just one or two healers.

2) As a side note, adding Parasites (Parasitic Shadowfiend) and Agonizing Flames to Grid helped a ton for P3/P4, too

3) Stop DPS on Ph 3 4 5 transitions to improve transition

Phase 1

Phase 2

1) Tanking diagram see attachment below. Green good, red bad. Note each Tank has a cricle around the point he can tank.
2) Concencus seems to be that flame tank should ignore illidan flame (pretty much) and focus on their own add which will cause significanty more dmg.

3) When a laser is on a tank's side he/she needs to realize it is the ONLY thing that matters.

There are three really simple ways to deal with laser (and really only 3 unless you count shield wall):

1. Do nothing because it isn't going to hit you... keep your rotation going.
2. Backup - you can always backup just enough to avoid by simply moving back.
3. Run across to the safe side.

Always yell on vent the name of the tank whose side it is on - and maybe add "coming right for you" if it is

4) If druid tanking will take more dmg |(healer note) but superior threat will all this to be nuked harder faster

5) will have to confirm this next time we reach Illidan, but I am pretty sure the OTs can kill the blue flames with spell reflect. Last time I did it I got a couple of 2k damage messages, even a killing blow message. After that the blue flames in the middle circle, where I was standing, were gone, while they still were burning on the outer circle, where the beam starts/ends.

6) OMEN was/is buggy in ph2 on agro, tanks have less than it records

7) Completely agree. Phase 2 the DPS burn is solely on the first elemental. Once the first elemental dies you can sustain phase 2 indefinitely. A good goal for the first elemental dying is probably around 80-90 seconds, which should be just after the first barrage

We made a change in our P2 position tonight that made raid healing much easier. Instead of a loose, random spread across the grid, we stacked into 4 tight piles based on group number, each out of range of the other. This made it so two quick Circle of Healing casts would compensate for each fireball

9) No they cannot crush
- No you cannot block their attacks so block rating/% is useless

Your only concerns should be FR Cap, Crit Immune, Hitpoints in that order

Phase 3

1) In phase 3 when he transforms into that huge shadowblast spamming thing (i refuse calling it 'demon form' since he's a demon anyway ) we have hunters laying frost traps and shamans earthbinding totems right below his feet quickly. Three seconds before the inner demon spawns we tell every warlock to chaincast seed of corruption on him (even the tank) and the mages to flamestrike the ground. Usually they are dead within 5 seconds unless 2 or more warlocks get paralyzed. If they get out of seed-range hunters can easily finish them off and melees don't need to risk running through the raid and to flameburst damage to other people

Phase 4

1) Ignore traps not worth the risk/benefit whilst learning
tank can use max buffs (LS etc) for first enrage and shield wall 2nd

Phase 127
Loot

Phase 1
Shear - Reduces the health of his current main aggro target by 60%. Use Shield Block to stop it.

Flame Crash - Illidan jumps up high and lands in a patch of blue flame directly underneath his current position. Deals 5k fire damage per second. 10 yard radius. Remains on the ground for 2 minutes.

Parasitic Shadowfiend - Random raid members will be targeted with a Parasites debuff lasting 10 seconds and dealing 3k shadow damage every 2 seconds. Once this debuff has ticked off, 2 Parasites will spawn at the affected player's location and attempt to melee whoever is highest on global threat (generally a healer). If they are successful in this melee attack, the targeted raid member will receive the Parasitic Shadowfiend debuff. Parasites have around 6k HP.

Draw Soul - Will drain targets in front of him in a similar way to Cone of Cold, dealing 5k shadow damage and healing Illidan for 100,000 HP. Shadow based spell. Resistible

PH1 is a tank n spank phase. Tank will move slowly whenever he needs to move due to flames, but otherwise its tank n spank. However!
The raid itself has a fairly easy job, DPSing Illidan down and keeping the Main Tank alive. The only thing to be aware of is his Parasitic Shadowfiend debuff which he will target a random raid member (including the main tank) with every 30 seconds. Affected raid members should move out of the main body of the raid, and ranged DPS should be assigned to kill the Parasites which then spawn, making sure not to be meleed by them, as a single touch from the Parasites will spread the debuff to the meleed person. Healers make sure to heal the 'infected' raid member. We will use a location designated by the raid leader for this position to run to. Hopefully someone will call out the debuff on TS to aid this phase.

Phase 2
The hard phase.

UPDATE :

Phase 1

This phase is now mastered.
The strategy is that the tank moves well out of the inner circles, and tanks there so that the blue flame patches will not affect Phase 2.
The mages will form one or two (Raid leaders call) teams for killing spawned adds. Infected players will be told a location to move to and the mages (with possibly some other AOE backup) will move to kill the adds as each player pops.
This is not a DPS race but a control phase, saying that I managed so pretty heavy threat on later tries when I was confident with the key points of phase 1, so this phase can be done pretty quickly if we work hard.

Phase 2
We are making some progress, its a hard learning curve for tanks, so bear with them. What people can do to help is watch agro and practice observance, nuking adds to take agro, causing unnecessary healer trouble wont help here. The raid needs to make this phase as easy to learn as possible, getting the first flame down with everyone alive will be a significant move forwards, I believe we actually have this in sight already. We just need EVERYONE to be doing what they can to help the tanks and healers. Its a very hard to tank and heal intensive phase.

Am I the only one having some perverse pleasure in seeing Feral suffer?
