Welp....this is my way of giving back to the community that has given me awesome skins and textures amongst great advice, I just want to show that I'm not a Leecher and give back in return =P.
So me and my raid group have been doing ZA every chance we get and this "bug" I guess you could call it has happened 4 times in a row now since I have noticed it the first time.
Do the fight as you normally would with.When the hatchers come up handle it as normal burn one hatcher real fast while the other side hatches his.Now we all know that when all the eggs get hatched you get a massive respawn of eggs when the next set of hatchers come.Well after the first set of eggs were hatched we just let the hatchers do their thing and hatch the rest of the eggs that are left....DO NOT! I REPEAT DO NOT KILL THE HATCHERS THIS TIME!...They will continue to "hatch" eggs that aren't even there, they don't aggro the group at all they just sit there as if there were still eggs there.As long as you don't kill them the eggs will not respawn and then your DPS can focus entirely on the boss for lots of ease.
I will just say this I do not know if we got super lucky and keep getting a bugged instance or not but just something for you guys to try out =D.Good luck and have fun killing him.
