Cata - Blackrock Caverns

If anyone gets 100 stacks they get MCd and it's a wipe. If any of the adds get 100 stacks they
Evolve and it's a wipe. Easiest way I found is setup the 2 chars that will be beam tanking
the side beams. Have them target their add and line them up so they are straight on.
Then get your other 2 chars wherever you are comfortable with (remember there is a fear). I have
also stacked 2 toons on each side and like that positioning it's really up to you.

Finally get your tank and be ready to pull. Use IWT at the start of the fight to get
your side beam tanks in position while moving your tank up to get threat and beam tank the
center add. MAKE SURE YOUR SIDE BEAMS ARE IN POSITION. Failing to
get into the beams right away will cause a wipe. Next use quick
IWT and keypress back to face the side guys to the boss so that they are looking across from each
other. At 80 stacks keypress forward out of the beams. Continue dpsing till the debuff
is about to fall off and keypress back into the beams. Do this 4 or 5 times
And you got her down.

Remember to interrupt the fear or stagger tremors. Beam positioning is
More important than dpsing. Worry about the beams first and dpsing 2nd.

I have tried this with my team and I simply lack dps. I manage to get him to 30% but in the end, I just can't dps him down from 100% to 66% and then from 66% to 33% without having 2 quakes, which is recommended. Also in order to make the adds die, they must remain near the boss so the tank basically has to stay. I have worked down a tactic for that and worked good. Just need more dps. Basically the tank eats the cleave but uses the cooldown (50% dmg reduct on 66%. then 40% dmg reduct for 33%), which guarantees the adds to eat his cleave.

Yes I tried to burn the adds down but they have too much hp, and I think the cleave killing the boss works better. Will try again when I manage to get more upgrades for my team. Yes I have even pulled off bloodlust from start, but then fail at 66%-33%. When using bl at 66% I fail 90% of the time on 100%~66% phase.

P.S. My dps was around 8k~10k. Mage being first, warlock second, shaman third. Once I get everyone to do 10K+ dps would be much easier.

I found this to be a difficult fight personally, but I eventually got it. Here's what I do which you may find helpful:

1. Never take a quake. As soon as he starts casting, strafe out. I always strafe left on all toons. In particular, if you get the chains down fast enough you'll never get caught.
2. Set the same key that you target the chains with '/tar chains' to broadcast to your mage's frost nova ability. When he casts chains, just spam that. Your mage will frost nova holding almost all of the adds in place. Once the chains are down, strafe out. The boss will then kill all the nova'ed adds.
3. The hardest part for me is: After strafing, often after a chains, getting the group to a reasonable location and facing the boss is hard. You could IWT it, but what I do is just run up to the boss, hit 'all follow' and then have them back up a touch. At this point you're a bit scattered so at least 1 or 2 will get hit by a quake, but you gotta pay attention because if they all get hit it's a lot to heal.

That's basically it. After much trial and error for me I can do this fight. Also thanks to Toned for the many tips.
