In our case we have BWL on farm (finally) and are up to the Emps in AQ. That's where the huge stumbling block is. We have recently started wandering into Naxx. Luckily most of our better players are attuned so we're able to field decent groups. We killed the Instructor our second night, but here's where it gets sticky.

So we have 2 boot drops from Raz, now obviously we want to get our phat Tier 3 (one of them has gone to one of our MT's so it's very understandable from a personal and guild interest) so we decided to try to farm trash mobs. The problem is we also want to get Anub down, so we currently have our attention severly divided. One night this week we couldn't get a full 40 so we spent hours on trash mobs trying to get up the Abominations (We got the rest). This is no walk in the park and people assuming "all" we had to do was kill trash mobs would have it easy. Not the case.

Compound this with waffling back and forth between the two some nights and you've got a problem. Luckily this week we've finally got BWL on a one night clear and we're able to get Princess down in one evening, but we've had a grand total of TWO attempts on the Twins. Guild opinion is very divided: Some of us want to kill the Emps and go onward and finish AQ, others want to work on Naxx.

Where do ya go from there?

Do Emps, you will need the coordination needed in Emps to clear most the rest the bosses in the instance.

You should do AQ. The extra gear and experiance will help you in Nax.

I would say finish off AQ40. Your raid is going to need that fine tuning on execution from Emps and positioning from C'thun to get very far in Naxx. Trash/Raz farming in Naxx would be good for one night at week though, just for easy nice items.

I agree, the coordination and length of Twin Emps encounter is a good training ground for the Nax further bosses. AQ is more forgiving than Nax, and your group needs the experience from somewhere.

Also you may have some armaments collected, and I am sure the ones with it would want to turn them in.

Anub'rekhan is easier than the Twin Emps. My advice since you are where you are now?
Take a night or two to learn him. There's a million videos and strats out there. It's not bad at all, and you can kill him. Take a night to finish Echoes of War for your people with t3 tokens -- the Abom trash is intimidating at first, so this will be a bit of an expedition, but it's worth it for the tier 3 pieces.

Take one night out of the week thereafter to kill Anub and Raz -- t3 pieces, especially for your tanks, will really help down the line, and you might get sweet weapons like Iblis and trash drop Servo Arm or Harbinger. But don't do anything else in Naxx until you have C'Thun down.

You should try and figure out what's going to lead to the least amount of burnout. For my guild it was attacking Naxx (we stopped with about 5 serious attempts on Emps - which bothered me personally, but so be it). The manner in which we approached AQ40 led to burnout from a number of our *very* core raiders, which is never a good thing.

Hm, why stop there? At least the grandwidow felt easier for me than cthun because you are not so reliant on every single member of the raid. At cthun one guy can easily ruin the try. Fighting Faerlina is imho less dependent on the skills of every raidmember as long as your dps and healing is sufficient.
Funnily we did not continue to do raz simply because our priests weren't able to cope with MCing the adds, moaning about the dependence on luck and so on...

Somewhere, Khazal is crying.

Ouch. So Razu and Anub are the only two fights in the zone feasible for "working on emps" guilds? Is that a coordination, a DPS thing, or an every thing.

We also haven't made it to C'Thun though :) As for the Instructor, it was pretty cool that our main MC'ers had Warlock alts, so they had some experiance micromanaging pets. Thanks to my hunter experiance I'm the backup and thusly have crappy gear eating up bank slots.

:(

Edit the... I give up: We've been on BWL since January and downed Nef sometime in May I believe. Our gear's pretty good. I don't think we've disenchanted any BWL loots yet. We still have some people in OK-Good blues. All of our priests don't have Angelista's Charm yet, so that's caused quite a bit of hub-ub :) We've been exceptionally lucky with Regalia, 4 so far (We had those players borrow another guild's instance for a week). We had two drop last week which is why I was so frustrated that we weren't trying to kill the Emps because now that means to get their weapons they will have to miss out on a week of AQ and then we're down two of our best Mages.
