I’m not a Naxx expert and have only killed Heigan six or seven times, but what I’ve noticed is that the reason raids have trouble downing him is because they try to do too much too soon; rather than be patient and stay alive. Here are my general guidelines for healers:
- Stay on the platform for phase 1. Clense the disease, and use your instants when inflicted with the spell casting debuff.
- Dive off of the platform at phase 2 and go to the first ‘dance’ spot.
- For the dance itself, do NOTHING else except stay alive until you’ve mastered it. No healing, no bubbles…just do your job to stay alive. If a party member dies during the dance it’s his own fault.
- Zoom your camera all the way out. At first, guilds may try assign a raid member for the rest of the party to follow. This works ok, but sometimes there is too much lag. I’ve found that a better way is for each member to pay attention to the ground in front of them. Wherever the flame just came out of in front of you, MOVE TO THAT SPOT. A flame won’t hit the same spot twice in a row. If you follow that guideline you’ll be in great shape.
- After the dance, start cleansing on your way back up to the alter.
- Rinse and repeat. It’s a long fight but you play it conservatively it’ll go quicker than it would losing 4 party members who are trying to do too much.
