Mission Accomplished! Finished it a 2nd time with zero wipes (though 1 or 2 deaths though, damnit!)

First boss: DPS him down until he does the chains. Immediately dps the chains down. Once they are down, Get everyone away from him, as he will be doing an AoE Nova-type spell. Continue DPS, rinse, repeat.

Second boss: I guess there is a strat where DPS keeps the adds from spawning, some crap like that. I just targeted the boss, popped Heroism and cooldowns and just blasted her, grabbed the adds with the tank as they popped.

Third boss: Very simple. Make sure DPS are NOT standing on that ring of grating above the lava as they will be 1-shotted once lava starts shooting up from underneath. Tank temporarily drags the boss into the middle to get about 5 or so stacks of the debuff, pull him out, DPS. Once the debuff wares off, pull him back to the middle, get about 5 stacks again, pull him out, DPS, Miller Time!

Fourth Boss: Easy stuff. Tremor totems or other abilities that break fear are your friend, otherwise, tank and spank.

Final Boss: You're supposed to CC the adds, but like the 2nd boss, I just popped hero, all cooldowns, blasted the bastard.
