Not much difference to Normal:

• Before the fight get some space around the boss.
• Shortly after you entered the fight, the boss will split into 2. So you´ll need 2 groups with a tank, a healer and the rest dps
• Both groups needing a player that always stays with the tank to absorb damage. The rest of the mechanics from normal do apply to the 2 encounters of the boss in heroic as well.
