Hello, I'm the guild leader of a small relatively social 10 man guild and we got started late to raiding this expansion. Long time reader, first time poster so bear with me!
The problems, Our dps seems to be to low in general, Venum is me, I had to switch from my geared elemental shaman to a hunter because of the mechanics of the fight, and am quite undergeared. But our fire mage only every does about 10k dps in full epics, and he can't interrupt well at all which is partially bringing us down. I've seen on here that the suggested dps is ~90k and we are well off that at ~72k.
Our raid comp (avg dps to the side)
Fire mage (~11k)
Frost mage (~13k) He is frost to make sure the adds never get close
SV hunter (~12.5k) <---- me in blues on this char
Rogue 1 (15k)
Rogue 2 (13.5k) <---- This is our add interrupter so her dps drops by about 4k due to movement
Prot paladin
Blood DK
Resto Druid
Holy Paladin
Holy Priest <---- Typically we have another holy paladin in this slot
Our rogues are by far and away our 2 strongest dps in general, but we have to have rogue 2 on the add for both interrupts, and because we are missing the fester blood by ~3 seconds. The other thing we "could" try is to only 2 heal it, but even now the tanks will randomly die, and none of our healers really have a strong dps (boomkin is about 10k). In phase 1 we are fine, before the 5th add spawns we're pushing him into P2, it's in P2 where things fall apart, last night we had 6+ wipes below 12% and that really seems to be our wall. The tentacles aren't getting interrupt fast enough/killed fast enough and we only have about 2 seconds of dps on cho'gall in between. We've tried all the strats, against the wall, in the middle, following one dps player on stalks, splitting the raid up between stalks, all of it. They just don't seem to die fast enough. Our best attempt we left the hunter on cho'gall and the rest of the dps on the tentacles, and it seemed to slightly improve the fight. I know we have some class stacking issues, but we can't seem to find decent players in the other classes.
Here are the logs for last night, there are several attempts with some sloppy mistakes by individuals like getting hit by crashes, or missing depravity interrupt but in general we can push P2 easily with everyone under 20 corruption 90% of the time. Also, on good attempts we push into P2 with our healers at 70% mana, but they are ooming before the 4th set of stalks.

What I need to know, is it a gear issue, dps issue, healing issue, or all the above? Should we learn to two heal it no matter what, even if our healers are at 25% mana in P2?
Any and all help is appreciated
