How to tank Chimaeron

I'll make this a more brief guide then what I did to Halfus.

Chimaeron has 2 abilities the tanks should worry about:
Break: A debuff he puts on tanks that increases physical damage taken by 25% and reduces healing done by 15% for 1 min. Stacks to 4.
Double Attack: A buff Chimaeron gets when he applies Break, which will cause him to strike twice on his next attack,

There are 2 very efficient ways to tank this, but both have the same concept behind them.

The basic concept is: 1 tank should take all the stacks of the Break debuff, while the other tank should take all the Double Attacks from Chimaeron. As for the 2 ways of doing this, the difference between them is very subtle. To better explain this, I'll use BT for the tank who takes Break (Break Tank), and DAT for the tank who takes the Double Attack (Double Attack Tank).

Tactic 1:
BT starts tanking until he gets the first stack of Break. After that, DAT will taunt, soak the double attack, and keep tanking. Later, the BT will taunt Chimaeron just befire he casts Break, and DAT will taunt back right after that, so he can soak the next Double Attack as well. Rinse and repeat.
How will the BT know when Chimaeron is about to cast break? Now here's the tricky part.
Remember the Break debuff has 1 min total duration. When it has around 48 seconds left on it, it's time for the BT to taunt and take the debuff. But it gets worse. If Chimaeron casts Massacre, the next Break will come around 8 to 10 seconds after he finishes the Massacre cast.
So to summarize, BT needs to taunt when you have 48 seconds left on the Break, or, 8 seconds after massacre.

Tactic 2:
Pretty much the same, but instead of the boss being tanked by DAT and being taunted of by the BT, it's the other way around.
BT will be tanking the boss, and DAT must taunt to soak the Double Attack, right after he applies the Break debuff on the BT. After the Double Attack is soaked, BT must taunt the boss back to him.

Which tactic to use?
I think tactic 1 will be more efficient, since the healers will be healing a tank without the Break debuff (which reduces healing by 60% on 4 stacks) for the most of the time. But, the timing for taunting takes much more skill and practice, and this may take several wipes before being pulled off correctly. On the other hand, tactic 2 seems much easier, but will put a bigger struggle on the healers.

In the end, it all depends on our tanks' skills
