'All in' is the general consensus on my server, but it should be said that (alliance setup allowing) SMNs and MNKs should remain outside. Walls won't stay up long enough for DoTs to be as effective as they will on Wolfsbanes and Cerb. MNKs will likely see GL stacks drop by the time they get minimized, are eaten, and zone into the belly. The other front-loading DPS jobs are better suited for all in approach.

I will admit that I always held the chains, but after reading a few posts about delaying the second belly phase, I won't be doing that anymore. At least not on the first belly phase. No reason to wake him if he isn't dead already by the second.
