Looking for advice here, if any have any...
I put together a one-time group from my raiding alliance to burn through Ulduar 25 and get ourselves the Ironbound drake meta. We've been extending for two weeks and picking them off one-by-one. Now, after crushing every other hard mode, we've hit a brick wall on One Light. Why? Because Sara is healing herself, and possibly Yogg himself.
Sara's health periodically increases, which means it takes on average 12-14 Guardians to trigger phase 1 if you time the explosions right. Worse yet, if you don't time them right and we explode the "final" one while she's casting (she can't transition mid-cast), she heals right after, and the phase could theoretically go on indefinitely.
Who cares about phase 1, right, it's cake? Well, unfortunately, no. Because it takes so long to trigger phase 2 -- far longer than it ever did back when we were wearing Ulduar gear -- by the time she flips, the adds are spawning very fast. That means we enter the transition with 4+ Guardians up. This usually means that not only do we start off right away behind on tentacles but we often have early deaths (tanks, melee from explosions, constrictors because DPS is split too much ways). We've seen that when phase 2 starts off this terrible, we never recover and everything snowballs from there.
The icing on the cake is that Yogg himself appears to heal between brain phases, although this is a little harder to confirm (at least one healing class was mind controlled and may be to blame). Even with us massively overgearing the encounter, the brain room team struggles to flip to phase 3 fast enough to avoid the already-behind-tentacle-group from getting overrun.
We're not a super elite group, but most of us are decent raiders, so I really don't think the issue is us sucking. Of course it has taken some work and learning and there is room for improvement, but we would have had this fight down already if not for the bug.
Now that we've spend over five hours working on him (for contrast, Firefighter took just over two), I'm ready to concede that we are incapable of beating him with the bug. It is heartbreaking after three weeks of hard work. As raid leader, I feel like I've really let the team down after all the work they've put it.
TL;DR: There is an obvious bug on Yogg that is making him difficult, if not impossible, to beat.
So what I want to know is:
(a) Have any of the guilds out there who farm 25man Yogg+0 weekly for the mount beaten him since 4.0.1? If so, how did you handle the healing?Tonight is the last night of the raid and if I can't come up with any solid ideas, I have to tell my raid that we're giving up.
(b) Does anyone have any fabulous ideas to try because we totally abandon hope of killing him?
FWIW, here are other bug reports on this issue: Here, Here, Here and Here. Blizzard gives a "this may be a bug but sorry we can't help you" response to tickets.
