I did this at 27th of December.
If some 1 want to do that, i can explain how.
First of all, fight is about moving boss to let the sparks collect behind the boss, and druids/palas roots/stuns them at same spot. Ideally u can wait for sparks that is going from same spot, so that will be more easy. When boss is about 50% u should have 3-4 sparks at same spot and kill them to nuke boss down when he lands.
Timing:
1st phase -In about 2m 30s u should nuke him down to 50% and with 3 sparks u should take him down to 1-10%.
2nd phase - u MUST stay on this sparks to nuke adds down. Prot warrior with spell reflects and DK with anti magic shield will help u to do that. If u will be lucky enough random shields can spawn to place where u stay. 2nd phase should take no longer then 1 minute, because 3-4 sparks gives too insance dps.
3rd phase - if boss have 1% then just 1st who attacks boss will kill him. If boss have about 300k hp left and u still have 30 sec left u can easily kill him(but with 10dd drakers without healers).
TIPS:
1. Move boss carefull to dont kill the raid if u want collect sparks behind the boss.
2. Try to take as many ranged damagers as u can.
3. Use not more then 2 healers for this fight.
4. When starts 2nd phase healers in this sparks must go all out dps, put dots up (and refresh it when he flying away, dots will keep damaging him but u will not see that).
I used setup:
3 mages(fire), 2 rogues(combat), resto dru, holy pal, DK, prot war, moonkin.
Recommend setup:
prot war, resto dru, 2 fire mage, moonkin, 2 BM hunts, holy priest, elem shaman for heroism, DK.
As u can see i havent used heroism or something, just skill and insane dps . Did this not with my guild just with some skilled friends and ppl who wanted to do so. Good luck with tries.
