Yeah 1/14 on 25 man is giving me heartburn. Honestly, this type of progress is not typical for our guild. We have enough players that we were fully supporting two 25 man Naxx clears a week. We have at least 25 people geared well enough for Ulduar who can meet "normal" raid time. Week 1 was unplayable. Week 2 had several issues going on. For whatever reason the people setting the schedule thought that changing for progression on the fly would be a good idea. As a result, a lot of regulars weren't able to make the ad-hoc scheduling. A lot of time was spent on Flame Leviathan trying to get hard mode working for us and we burned a lot of progression time we could have been spending on learning other bosses. On top of that, our guild master who is usually heading up the runs had a death in the family and was gone during the latter half of the week, which is when we normally raid. He's back and I think some of the scheduling conflicts are resolved and we're going back to the 25 man raid schedule that was working for us pre 3.1 patch, which is 3-5 hours 3-4 days a week for progression focus. The fights I was in on (the schedule changes messed with my ability to attend) were Razorscale and XT. For Razor, it was our early attempts and we were figuring out positioning. We just didn't have enough time on him to get it down. Our DPS numbers were looking appropriate to succeed... for XT, we were having lots of problems with people understanding what to do when they had gravity bombs or light bombs and people weren't burning the little robots in time. A lot of times people were doing the opposite of what they should do. We hit the enrage timer multiple times with the boss only a little under 50% -facepalm-. We have 2 successful 10 man groups running (us at 7/14 and the other at 6/14) and a third one that we know will sucesfully launch now that our guild leader is back.

Anyways, back to the original topic... To take a fresh perspective, let me think about the bosses I have seen go down and here's my thoughts on multi-box viability:

Flame Leviathan - I could see 2 boxing this easy mode. Put 1 toon in a siege engine and make the other toon a gunner. Have your active window be your gunner and target and fire with number keys. Move the tank with keyclone (or whatever broadcasting method) movement keys.

Ignis - Boxable with practice. Might have some issue getting through the trash avoiding the cyclones. Should be pretty easy to move out of the flame circles.

Razorscale - Boxable mainly if DPS. Movement not much different than avoiding void zone type issues like in OS.

XT - I see challenge here. Do I stand still? Do I move? Which toon do I move and in which direction? Do I need to burn the little bots or focus on the heart? The answer can be different to the same question for each toon.

Kologarn - I'm worried about reaction time to move out of the eye beam. I feel the eye beam makes this fight about equal to Thaddius in terms of maintaining a good multibox output.

Auriya - Probably the most boxable boss I've seen... Nearly all of the work is in the initial pull. If you have a shammy w/ a tremor totem, the difficulty level of boxing goes WAY down, especially if the summoned cat doesn't get killed and you don't have to worry about a void zone.

Thorim - Hrmm.. to box the arena or the gauntlet. I've done both sides and I'm not sure which I'd prefer to box. Probably the gauntlet. As it was, I was having huge problems pulling aggro in the arena on my lock and I had to switch to more single targetting than AoE. Right now, I don't think I'm comfortable boxing this, but it's probably doable with more experience.

Freya - First time I saw this boss was last night. I haven't seen her go down yet, but I'm very skeptical on multi-box viability at this point. I might feel different later.

Reading through the descriptions on bosses yet to come, the deeper and deeper I read into Ulduar on bosses I haven't downed, the more I think "not boxable". I guess experiencing the bosses first would be a good thing before I start complaining about difficulties in boxing this in the future. ^^
