CA Raid Squad managed to nail every aspect of this fight in just one attempt the other day, aside from the DPS requirement to beat the enrage. In fact, it was quite a ways off from beating the enrage, so this thread is going to be about improving everyone in the group's DPS.
Our combat log for this fight is here:
http://www.worldoflogs.com/reports/tz3c ... 113&e=5420It may not be the most representative log, but it's all we have right now. The math is very much against us right now as it's somewhere around 8k dps per person with 6 healers and 7.5k dps with 5 healers. I am very certain our group can 5-heal this fight with the proper use of tank cooldowns so 7-7.5k dps is what people need to shoot for.
As far as raid buffs, in this attempt I think the only thing we're missing is an attack power buff (provided by a hunter, enhance shaman or blood dk). I'd think Phelix switching to enhance for this fight would make the most sense.
Also consider the use of battle rezzes -- we had jed get rezzed and die multiple times. Why? Because he didn't have his three spore stacks when he got rezzed. So if you're going to battle rez, only do so immediately after he exhales the gas and no spores have appeared. Though one death is almost certainly a wipe at enrage anyway.
