This is by far the best outlined Hellfire tank strategy I've yet seen, and for the first time I can see it repeatable and workable. I think we tried Hellfire exactly one time (our first 2 weeks were black/red) and said 'yeah, don't think so'.
Obviously this is very much a 'fit to guild' thing, from what I'd seen Hellfire tanks didn't 'feel' sustainable.
It is a "fit to faction" thing. The paladin is there for Concentration Aura. Aura + Intensity = 105% uninterruptable hellfire. I would even include a second Paladin at the expense of the priest for a FR aura.
Paladins don't have Prayer of Healing though, and self-inflicted Hellfire damage is not resistable. Prayer of Healing helps to keep the strat mana-efficient. Done properly, drakonids won't get many chances to even use their special abilities anyway. Though, I think that fact is more a matter of the strength of my guild's DPS than a strength of that particular strategy.
I think the FR aura comment was more for the drakonids abilities, not for hellfire.
We use a very simple, non color-dependent method for phase one. It has made Nef by far the easiest fight in the zone (yes, even easier than Ebonroc).
We gather the entire raid up on the throne. Warriors stand at the base of the ramp a little to the left (if you're facing out from the throne) so they are between the raid and the two spawn points. Rogues stand at the base of the ramp about 10 yards behind the warriors.
Start the event. One warrior starts spamming battle shout (all the warriors are in the same group, to get max aggro benefit from the shout). A separate tank pulls the Chromatics to the rogues, who burn them down. All AoE dumps their spells on top of the battle-shouter. The mobs die well before they can get through the AoE. Watch the bodies pile up while the rogues continue to deal with the Chromatics as they spawn.
Welcome to phase 2. The best part of this is that all the mobs will spawn at the same point for the 20% zerg and can be instantly mowed down.
We use a normal raid (five of each class). Five warlocks and five mages will provide more than enough AoE for this strat to work flawlessly. There are no "hard" colors. It really is as easy as I made it sound.
We always use intensity Warlocks to AOE sides, no matter what colors we get. But we're Alliance w/35% concentration aura from Paladins.
If we get Black/Red, put them on black. Setup 3 Warlocks to spam Hellfire with 2 healers on each 'lock. An additional 4th Warlock stands back and spams CoE on each new target to reduce their resistances to fire.
..and we stack lots and lots of melee on the side Warlock's aren't AOE'ing along with Imp. Blizzard Mages.
I've personally always been a fan of the FF method. Our guild was having a huge problem with the AOE strat, but once we started using assists (Almost always Mages because we have approximately one billion) we mowed through phase 1 no problem unless healers were slackers and then we might lose a warrior/rogue or two. Your DPS -HAS- to be on top of everything because loose drakkonids completely mess up the strategy and they can add up quickly and lead to a wipe, or at least close to it.
The way we do it is we have three warriors on each side picking up the mobs. Two of them get the little drakanoids, the other one tanks chromatics. There are two people who pick out targets on each side and you assist those guys to kill their targets. If we start get overwhelmed, we call an AoE and we burn them down. Then we transistion into stage 2.
We do a naked run first to find out colors to figure out which would be the best way to make the raid into which group on which side. I think we're going to shy away from this and we'll just wing it in a couple of weeks.
My guild splits the raid into Melee and Ranged groups, and we focus-fire on both sides. Healers and tanks are split equally with our MT and primary OT on opposite ends.
Draks with nasty melee effects (Red, Black) get the Ranged DPS treatment while Melee handles Green/Blue/Bronze.
We also assign 1 DPS Warrior per tunnel to Solo the Chromatic Drakonids. Typically our Priests will toss up a few SW:P to help burn the Chromatic down, and 9 times out of 10 the Warrior will have finished off the Chromatic before the next one on his side spawns. There's really no reason to target the Chromatics with an Assist-train.
I'm from Mizpah's guild (Enigma on EU The Venture Co) and I'd just like to say that we did it! Tonight was our first Nefarian kill. With the dreaded blue/red combo, no less.
Thanks a lot for the comments. The single target DPS on both doorways tactic was the first to get us consistently into phase 2 last week, yesterday it's gotten us into phase 3, and tonight it's gotten us the severed head of Nefarian.
