1) The Rath Council
2) Xegony
3) Coirnav
My guild is "A family raiding guild". We raid 4-5 times a week, but attendance is optional..
Based on how we have done on these so far ( 0 for 3 vs each, but came closest on #1 and #2)
I would say of the 3.. Xegony is the least hard, followed by The Rath Council and the hardest being Coirnav..
Many of us now have the alt time key [as several members ARE fully flagged and we are doing joint raids with another guild to get those that are not their alt flags]. This is allowing us to sort of attack getting fully flagged on 2 fronts.. ( i.e. getting gear via the alt method to allow us to still get in the legit way. hehehe)
