This thing is truly a joke, Idk what we did but we had lamia glitching and not attacking anyone, even the zoner while we killed the babies. Here's how we did it. btw we had 8-9 people with 3 outside just to keep the zoning going, the 3 outside weren't in parties.. that way the whole zoning party doesnt have to zone, just the individuals. Also stay very near the zone since mummies repop in the tunnel.
-Important note, do NOT NOT NOT cure the zoners whilst they have hate, only cure them once they come back from zoning.
Walk all the way past Nuhn's ??? and zone out. The popper disbands before popping and pops it solo. (there is a ledge so he will have to be tractored) Another person outside the alliance grabs Exp. Lamia and zones it, next person zones it, and so on until it pops the babies. Now do the same thing, 1 person zone lamia outside of party. While this happens your main tank will grab one of the 2 SAM lamias (I always save rdm for last jic) Then just zerg it, wait for another zone if needed, grab next sam, kill, grab RDM. The SAM lamias are a complete joke. the RDM.. its a good idea to have rampart ready and throw on some MDB magic dmg -% gear just to be safe.
Idk how but through all this we got lucky and exp. lamia just stood there so no extra zoning was required, but always play it safe. So once you have all 3 babies down, it should just be a Zerg on the main bitch. I tanked with earth staff pld/nin from a distance so it could only Ranged att me, we NEVER saw a charm except for once and it didn't do anything. Make sure mages remove para and do what mages do.. and then you win, best of luck on drops!
EDIT- to be more job specific we had 2 plds a whm a handful of blms 2-3 rdm/brds and the rest DD.
The only really important thing is NOT curing the outside zoners whilst they have hate, on our first learning try we had to keep zoning it until we recouped, so just keep that in mind at all times.
