We are currently also working on Thok. Had a few attempts where we managed to kill the bats with only 1-2 people dead. The other attempts were mostly phase 1/early bat wipes.
Our cooldowns are:

The healing seems really tough for this fight, more tough that it should be with our gear/the gazillion cooldowns assigned. We frequently waste attempts in phase 1 because 3-4 people die to a shout randomly, is there something we are missing healing wise? Also, is having 10 melee and only 6 ranged dps in your group a problem in 25man? Lastly, should our warlocks spec out of destro for this fight? Looking at top WoL logs for this fight destro seems to do comparable damage to affliction for this fight but our warlocks are complaing allot about not having many instant attacks as destro, how are other destro locks handeling this?
