What classes, in particular, ran out of mana?
If I recall my first experience... a guildy and I each played a couple characters and our makeup was:
War
Monk
Bard
Cler
Ber
Shm
Mag
We stashed the two healers under the bridge (mentioned several times already), and they kept the warrior up (with the help of mana clickies).
The tough factor was the raid damage. The biggest boon to us was solo auras. The lifetap proc helped immensely with raid heals. My advice to you is have your healers focus on the tank and figure out a secondary healer to keep the raid alive. Lifetap procs are a great start. Necro group lifetaps are a huge help, also.
Overall, though, I'm surprised Sleeper lives long enough for you to go oom with 12 players in the raid. What are your group setups and buffs, and do you buff in an order that puts the best buffs in the higher slots to preserve them from the dispel?
