Preparation

Assign the Main tank to Attumen, and an other tank to midnight. Healers should split evenly

Strategy #1

Begin the fight by having Midnight's tank attack first. Start DPS when threat is built.
When midnight gets to 95% life, Attumen joins the fight. Attumen's tank should have some Rage build up already from Midnight's fight t be able to pick up Attumen quickly. When on the tank, point him away from everyone to avoid the Cleave. Tank both bosses a little distance away from each otherand never face Attumen towards the raid.

All DPS should be on Midnight. When Midnight gets down to 25% life, Attumen mounts him. Attumen's HP is based on his previous HP while unmounted and he resets his thread list.
The main tank needs to pick him up and turn him away from the Raid as quickly as he/she can. Give the tank a few seconds to build threat and start DPS.
As soon as he is mounted, Attumen gains the charge attacks. Make sure everyone is a full life in case they are charged, and top them up right after it happens.

Keep Attumen's tank alive, don't let anyone die to charge, and DPS him for the remaining percents.

You can avoid the cleave if you stay behind him. (except the tank of course)

Strategy #2

You can try to split the DPS with the tanks between Attumen and Midight. It can be helpful as Attumen;s life when mounting Midnight is based on both his and his horse's current life. If you you get both of them down low, he'll have lower life when he mounts Midnight.
