1 tank, 3 healers is ideal. Note that we beat this timer with a full minute to spare -- this is with my off-tank in the raid as well as several brand new 80s. Beating this timer is 100% about the sparks, and while gear will help a lot, it's not enormously necessary. You do, however, want all of your raiders to have ~18k health minimum while fully buffed to handle vortex and varying amounts of raid damage.
Phase 1 Notes
When Malygos is landing, he doesn't seem to register threat/damage for the first few seconds. Burning long cooldowns such as Bloodrage and hitting him too early isn't necessarily good. Have your raid give you a couple seconds until he's clearly facing you.
Like several of the Blue dragons, Malygos has no tail or cleave attack to worry about. For this reason, you can move him without too much fear of hitting other raiders (though you still need to pay attention to his conal breath).
You have plenty of time to move him away from sparks and force the sparks to cross over the raid. This is why I move around the edge of the inner circle, which also prevents him from facing the raid for a breath. When there are two up (the one from before the vortex and after) and when they are coming from adjoining quarters, I triangulate Malygos' position so they're both forced to cross the center.
It is possbible for Malygos to be within reach of melee who're in the center spark field while still allowing Hunters to attack from within the spark. This will happen naturally so long as you use the outer edge, though if you have problems, cut the corners a bit tighter.
While Death Grip from Death Knights is a means of stacking spark fields and while this strategy will work for some guilds, it will not be a recommended strategy given that you're relying on one specific class and you're making an entire raid move instead of just the tank.
With that said, tanks who are not used to strafing, mouse movement, camera control, and effective keybinds need to step up their game. Fortunately this website is here to help with that.
Phase 3 Notes
This video isn't a stellar example of Phase 3, in part because I don't see combo points on my interface (in general I'm very unhappy w/ my interface atm, I need to work on several elements such as player frames, target frames, and buffs). However, you do see my successfully shielding from a Surge, which is by far the most critical part of Phase 3. Make sure everyone in your raid clearly understands how to use that ability.
Did you have any trouble with holding threat without the damage buff while the DPS had it?
None. The only place where aggro is tricky is in the first few seconds when he's landing at the beginning of the encounter -- he doesn't seem to register damage/threat for a few seconds, so burning Bloodrage and an ability too early caused issues.
This looks like its going to be lots of fun. It also looks like it is going to tax my PC...
As for movement whilst tanking, PvP skills have taught me a lot towards that. Your right mouse button is your friend.
A little help, though not sure how much it will be, if you ever find your self running out of fingers, and you are fast enough on the button mashing, you can use your W (walk) finger to hit a button if you jump, then quickly hit the button you want, then back on W key before you land. With this you continue to move with out stopping and you get your ability off.
Can't say I have used that whilst tanking, but in PvP I used that a lot.
If your fast enough with it you can even talk with out stopping (or hitting auto run), I can get off simple small words like yes and no.
Another tip for phase 3 is not to target malygos while falling through the air onto your drakes. We did this last night and for some people the shield would not work. You can target him as soon as you land on the drakes. It seems odd but it does work.
=> We initially learned the 3rd phase by asking everybody to just heal, ignoring DPS. Also, move far away from the boss and the phase starts. That allowed people to become aware of what the fight looks like and get aware on how to use the shield, instead of dying in 10 seconds because they are overwhelmed with new information.
=> Blizzard's default UI is great to heal, since GRID and similars won't work. Drag the groups from the raid panel to your preferred location and use that to heal. Also can be used to warn people that their energy is too low.
=> For the 3rd phase, 2 healers is enough if the raid stay stacked and people use their shields. Our first kill was actually with only 8 people alive, we lost 2 at the end of 2nd phase due to unlucky shield spawn positions. So, 6 DPS and 2 healers for the 3rd phase is fine if you get there with 3 minutes spare.
=> Remember that stacking the flame debuff called 'Engulf in Flames' is your main damage source. Get that stack as high as possible, but don't be fooled to think the best initial rotation is 1-2-1-2-1-2, too much usage of 2 (Engulf in Flames) at the start will let you energy starved and your stack will have short duration. A good way to start DPSing is with a big 5-point combo to give you a 22s stack, and then work on stacking it up fast: 1-2, 1-2, OR 112, 112, as much 2 as you can and your energy permits. Always save 25 energy for the shield. Don't be afraid to just wait for energy to build, remember your stack is slow and you can wait.
=> For healing, just around go clicking people in a round robin fashion and putting hots, if someone in particular needs more heal, stack more hots on him. Remember to always use your finishing move which heals all the raid (you're stacked, remember?) and gives a +50% heal buff, NEVER let it down.
Hope that helps, cheers

I haven't done this fight yet (guild still leveling) but the abilities you gain in ph3 when you get on the red drakes look exactly the same as the ones you get whilst doing the wyrmrest daily above nexus. I'm just guessing this, but if anyone in your guild wanted to familiarize themselves with using the abilities, make sure they have a go at this daily.
Think this is the quest: Aces High! - Quest - World of Warcraft
Edit: awesome video guide, only thing more I want to see is the disc flying, but obviously thats hard to do from a tanks PoV.
