Slagworks Melee Perspective

After having run the new raid finder wing on my tank, I took the DK out for a spin. This went a bit less smoothly (I hope it doesn't sound arrogant, but I find things go better when I'm tanking, usually,) as we wiped on Gruul when the tanks tried to take Inferno Slice on their own, but overall things went ok - though I did die to Oregorger because I wasn't paying enough attention to where he was rolling.

So anything particular to note?

Oregorger:

First off, I think Gruul might be locked until you get Oregorger down (likewise Blast Furnace, of course,) so this seems to be boss one, despite the fact that I think Gruul's the simpler fight.

As melee DPS, the two things you really need to look out for are the rock bombs he throws and the Blackrock Barrage that you need to interrupt. He does this I believe three times in a row, meaning you'll only be able to interrupt one of three. Given that it's not easy to coordinate LFR, I'd recommend picking 1, 2, or 3, and interrupting that spell, though if it becomes clear another player has chosen that number, try another the next time around. Be sure to get away from the little rock bomb things - they take a couple seconds to go off, giving you just enough time to get away (though it can be hard to see where they land when there's a bunch of melee.)

On phase two, learn from my mistake and be sure to be aware of where Oregorger is at all times - his roll-over and stun deal a bunch of damage, and that's on top of the wall-hits (which get more powerful the longer he's up) and the fact that you'll often be out of LOS of the healers. So be careful.

Gruul:

You're at the mercy of the tanks to an extent, but be sure to stack up in a big group to share the inferno slices. The main thing that you get that tanks don't is Petrifying Slam. When you get hit by this, spread the hell out before it goes off. If you do, I think you don't take any damage at all, whereas if you don't, it's going to hurt.

Blast Furnace:

On phase one, dead Engineers will drop bombs that you can voluntarily pick up in order to blow the Heat Regulators. Be sure to interrupt Engineers when they're repairing and kill the Bellows Operators - lots of AoE on this fight, particularly in this phase.

On phase two, I think the protection buff might not be a thing on LFR, so just go to town on those Primal Elementalists. Try to interrupt the Flamekeepers' Cauterize Wounds, as that heal will slow you considerably (and the healers are going to be gasping for mana.)

Phase three you want to burn as quick as you can - I'd actually recommend saving Heroism/Bloodlust/Time Warp/Ancient Hysteria for this phase, and if you have any long-cooldown abilities this is when to blow them - though given how long the fight can last, you might actually have been fighting a full ten minutes, so it's possible that you can re...30% haste buff thing and pop stuff like Army of the Dead and such a second time.

Elemental Runes:

If you're on the Legendary Chain (and somehow it feels like less of a pain than the Pandaria one - maybe it's the lack of PvP,) bosses in BRF will normally drop 9 Elemental Runes, but they have a chance to drop 27. You'll need a total of 900 (300 for each Elemental Tablet.) When all four wings are open, there will be ten bosses, meaning you will be able to get 90-270 per week (most likely somewhere in the middle.)
