Dance lessons from Nax

Well Basicly noticed that a lot of people have difficulties here and in the end only 4 of us was left alive to combat boss!
So we all know which one we are talking about but for people who were not there its the second boss of plague quarter - Heigan the Unclean: A Necromancer specialized in diseases and dancing or so says wowwiki. SO we need to dance with the specialist!
Boss starts in the green circle to begin with.
Black lines divide safe zones and red line represent the arc I bealive is the safest for all: to escape flames and that ugly debuff!

Phase one:
Tank pulls boss to red circle in safe zone number 1 (other zones (2,3,4) will be covered in flames. Melee DPS stands with tank and do dancing during this phase, and healers/ranged DPS goes to the boss initial position (green circle). Boss should be tanked facing the zone 2. Now this is VERY important. Boss have, let me put it this way: ''wide arms reach'' so more often then not he will be staying on zone borders. Melee DPS should never stand in the place where boss stands but in place of the numbers (or in the middle of the zones). So when lava erupts melee and Tank shifts to zone 2 (remember to stay in the middle of the zone). Eruption again we shift to 3,.... If I remember correctly dance in phase one lasts in this order:
1-2-3-4-3-2-1-2-3 At the last zone (3) boss shifts to green circle again and commenses
Phase two:
All party members should run to blue square (which are forward positions) in safe zone number 1. Now eruptions will be much faster in rotation and it imperative that you start run from sqare position, and not from numbers positions from phase 1 (meaning close to the border of the zone) in order to complete the run untuoched. So again the dance 1, lava eruption, shift to 2, lava eruption shift to 3,......When you hit zone 4 stand on purple square, they are returning positions. If I remember correctly dance in phase two lasts in this order:
1-2-3-4-3-2-1-2-3-4-3-2 At the last zone (2) boss comes down again and restarts the phase 1.

While running about I use platform corners and middle as orientation points!
Please share your insights so we could all have it easier inside and get the achievment of whole party living through ordeal:)
