My guild is 5/13, and I'm pretty sure we average around 363ish gear or better. We tried Beth'tilac tonight and spent about two hours wiping on her...we're not even making it to the burn phase.
We have a bear tank, holy pally, and enh shaman going "upstairs" and they more or less seem to have it under control (They're still having some issues falling through the web but I think that may just be a matter of practice?)
Downstairs we have a warrior tank (me), holy priest and disc priest healing, with a hunter, boomkin, ele shaman, and fury warrior dpsing.
We taunt down the first four spinners, and they go down easy enough. Once the first drone comes out, I pick it up and bring it close-ish to the raid and face it away, keeping it to the southwest since spiderlings don't seem to come from there. The warrior helps me kill the drone while the ranged kill spinners and spiderlings. The spiderlings seem pretty clean, don't get any stacks of consume unless people have already started dying.
It feels like damage is just out of control. I'm trying to mitigate the aoe she puts down when no one's up top, but it feels like I'm getting hit pretty hard. We seem to start losing people after the first or second smolder and it's downhill from there.

I'm afraid I suck at reading these things (officers generally do that)
Was hoping I could get some insight. It's really frustrating cuz so many people are saying that this girls got a relatively easy learning curve.
