Lemmings of the Light

As there are 4 achievements for the Drake in this section, I'll discus the two for Flame Leviathan and XT-002 in this part first and will update it with the two for Ignis and Razorscale at a later date.

Orbit-uary (Flame Leviathan):

A very nice guide on how this works can be found here: http://wow-achievements.com/blog/2010/07/13/glory-ulduar-raider-10-player/

Note that this guide is written post 3.3.5, so it should be accurate for the gear level we're currently having (since vehicles boost with gear lvl nowadays). Since knowing how to use your vehicle in this fight helps very much, I'll add the vehicle and position to the line-up when I make that, so that people can look up about their role in this fight (if you have preferences to which position in which vehicle, please let me know).

Priority of the DPS should be: Ice Blocked persons (if any), plant adds, Pyrite shooting (siege gunners only), flame leviathan.

Heartbreaker (XT-002):

For this achievement, we need to break the heart of XT-002 and then defeat him. As of now, this shouldn't be too difficult. The setup I would like to use for this are 2 tanks, 2 healers, and 6 DPS. So we'll need a healer with a dps off spec. Once the heart is broken, the OT should tank the Light Sparks away from the raid (taunting them and hunters using MD) and the ranged kill them off. The rest of the DPS focus on the boss and burn it down.

Since taking out the heart in 30 sec is a must, all cooldowns should be ready when the boss is at 75% and exposes it's heart so we'll burn it down.

Iron Dwarf, Medium Rare (Razorscale):

A surprisingly easy achievement. The goal here is to get 25 Dark Runed Guardians killed by the Flame Breath Razorscale does. In the air phase of the fight, have the ot take the Guardians apart and one or two dps bring it down to 15k HP. Then, once Razorscale lands and phase 2 begins, have the ot bring the Runed Guardians to the front of Razorscale untill she uses Flame Breath and kills them.

The best part about this is that you do not need to kill 25 Runed Guardians in one attempt, so if the boss gets killed before we roast 25 dwarfs, we can continue that on our next encounter with Razorscale and the counter will be where it was (for example 10).

Stokin' the Furnace (Ignis the Furnace Master):

Well, very easy using the Zerg tactic we always use on this boss these days. No more explanation needed I reckon.
