Iron Assembly DPS Perspective:

I took the DK into the new BRF wing today. There's not a huge amount of new information to worry about, but I did get a bit better insight into a few mechanics.

Beastlord Darmac:

This fight is more or less the same. You'll want to DPS down any of the spears that are pinning raid members. The packs of beasts will go down relatively quickly, but you should most likely go into full AoE mode on them. Also, when he's on the Wolf or afterward, try to run away from him as he jumps away and back for Rend and Tear, as you can avoid getting stacks of the bleed this way.

Operator Thogar:

The best advice I can give is to keep your camera pointed at one of the two rows of doors. The most important thing is that you not get hit by the trains. If you need to stop DPS in order to do so, do it. Remember, a dead DPS does zero DPS. There are many adds here, so go full-blown AoE on them. Interrupt the heals if you can, but don't worry too much about it on LFR.

Iron Maidens:

This time I got a significantly new experience, as I was assigned to take the hooks to the boat.

One tank, one healer, and four DPS will need to take hooks to the ship in order to stop the bombardment - be sure to assign this ahead of time, as on our first attempt we wound up with no tank (which actually wasn't the end of the world for Gar'an's crew.)

Jumping to the ship will give you a group of adds to deal with. You'll need to kill the adds and then sabotage the turret's ammunition feed (by right-clicking on the bombs there,) which will then blow you back onto the main platform and end the bombardment phase.

When Gar'an jumps, you'll have two adds - one is a shaman who casts a shield and a lightning bolt. Kill this one first, interrupting the shield, then focus on the hunter who will fire at random people.

Source's adds consist of a single big elite and several Eviscerators. The Eviscerators will fixate on random people, so kite them and slow/stun them. There are to to start with, but I believe more will spawn if you kill them, so just take down the big add and blast the ship.

Finally, Mar'ak's add is just a single Dire Orc. He'll cause pools of corrupted blood to show up under each player on the ship, so you'll need to be moving pretty constantly.

On the main platform, make sure that you run to the edge of the room if you get Rapid Fire on you, and try not to drag the circle over other people. It's pretty slow, which means you can actually slow down and let it catch up to you a bit if you want to make a sharper angle (and not drag it into a healer or something.)

Finally, if you're melee, you're probably going to just have to stay away from the turrets on the last phase and let ranged deal with it. If you are ranged, your number one priority should be burning those turrets down ASAP. While the fire can be dodged, there will be far too much of it before long, and it quickly stacks up a powerful DoT on anyone it hits.
