My guild just defeated Fankriss for the first time (yay battle shout strat!) and had our first pulls on Huhuran last night. I noticed that she paths really really really far away from the tunnel to the next bosses, so after the raid was over I just casually walked unstealthed into the next room. No aggro, easy! I stealthed past the Anubisaths and made my way to the Twin Emps room and pulled them. I immediately vanish and the bosses reset, but I quickly get demolished by the 5 Anubisaths that just ported into the room.

Now I'm wondering if Huhu got pulled too, because I died so quick she would have not had time to fly into the room. I managed to convince a fellow Rogue to start the Twin Emps fight while I stay in Huhu's room. Fight starts, Huhu doesn't budge, Anubisaths come and skidmark me out of stealth.

There is one last thing I can't test, which is why I'm posting here. Does the door in the Twin Emps room open if you haven't killed Huhu first? If it does, she's optional!

I'm not really concerned with why someone would want to skip her, just if its possible =)

*Apparently* its possible to get past her. Im not sure if this could ever be done by a 40 man raid though, or even some warlocks to summon the rest, and im not sure where you would stand to kill the Defenders. I dont think its optional no.

no she's not, there would be no place to kill the anubisaths if you did.

Isn't there a door between the trash and the emps? Does it only open if Huhuran is dead, or is it just a doorway with no door?

I rephrased:

Why would anyone want to bother with skipping over Huhuran and going straight to Twin Emps?

If you're still learning her, you may likely not be ready for the Twins.
If you're farming her, she's nothing more than a 5 minute walkover and some free loot.

How much room do you need to kill the Anubisaths? I didn't watch their patrols carefully, but there seemed to be ample room to fight them in the first hall. That's assuming they don't all path there eventually though.

What about pulling them past Huhu into the previous rooms? When they came to kill me she didn't seem to care (I was standing in our pre-pull prep spot for Huhu). They seem to act really strange when I pulled Twin Emps, like boss aggro. I'm curious if sending in a sacrifical hunter pet would be sufficient to aggro the whole raid.

Edit: There is no door, just a doorway.

A few patches ago at least the door to the Twin Emps room was always open. One of our Shamans used Far Sight to scout all the way down there from the entrance. I wouldn't recommend it though, it's some very precise timing to get past Huhu without stealth as her aggro radius is very large, though it could perhaps be managed with some invisibility potions.

That and it's not that hard a fight, you just need at least 15 people with good NR. Or 13 possibly, depending on whether you have your tanks wear normal tanking gear or not, that's really not that hefty a requirement.

About the Anubisaths between Huhuran and the Twins, they do indeed aggro like bosses do. Once they're pulled the entire raid is in combat with them. How they end up in the Twin Emps room is unusual though, they literally teleport inside. We figured that out after an instance reset once.

I imagine dealing with the Defenders would be an absolute nightmare with her still alive (i know we tend to use a large portion of her room when we pull them, especially on plague variants).

You could probably sneak by, but the time wasted sneaking around and wiping and summoning people back, etc, would really be better spent on Huhu. The Huhu fight is really not that hard now that all the craftable NR came out in 1.11. Just get 16 or 17 people geared up to 315 NR and go over positioning in advance and you should be good to go. I wouldn't expect to get very far on the emps if you can't master a much simpler fight like Princess Huhuran. Honestly, I would say the post-Huhu trash is probably harder than Huhu, now that decent NR is available.

You should try working on Huhuran when you're only source of NR gear is Maraudon, Green Dragons, and the odd drops from early AQ40 bosses. The introduction of craftable NR gear for nearly every slot has practically trivialized the encounter. Grab the bull by the horns and take her down.

I suppose the reason to do it would be the same reason someone 5 manned Onyxia, because they could.

While I have no clue if the door past the emps would open with her still alive (I doubt anyone knows, or has even tried yet) It would certainly be possible to get 3 people into the Emps room and summon everyone, and then pull the Defenders into their room, it's plenty large enough to handle Thunderclap/Plague (though the bugs would make it risky to use AoE's when dealing with the summoned adds. It would be a bit more tricky to handle the pulls from the tunnel before Huhuran, you'd have to sneak a hunters pet through without aggroing her. I wouldn't suggest trying to fight the Defenders in their hallway without precise knowledge of their roaming pattern though.

In theory, the majority of bosses in MC, ZG, AQ20, and even BWL and AQ40 are optional. You can probably get a summoning group past the 3 drakes to Chromaggus and tank him inside his starting area, same with Sartura, Fankriss, and Huhuran. They're nothing some extensive kiting a SS'd Warlock and 2 hunters/rogues can't get past ... Though, Boss order exists for a reason, if you can't kill 1-4, you aren't going to handle 5 all that well.
