Yeah have to agree with above posters... disappointing item as a whole. Stun Resist is okay but just not the HP/Mana that I feel it should have. Vule event isn't really one that is intended to offer upgrades to a guild, primary purpose is for the progression through DSK to DP of DoDH.
All of the Demi curse mobs drop the same kind of loot. While shyra, and maybe bloodeye are worth farming for lower end guilds, most higher end guilds will just kill vule for the flags, and consider the loot a bonus.
Most of the curse mob loot went to low dkp people or apps, although I opted for the helm, because I needed detrimental focus, and it was less dkp than the anguish one (which was still going to high dkp people at the time).
By the way, once you get the strategy worked out, vule isn't hard at all.
Yes we have had 2 flawless kills of him in a row now. I myself have been on the lever team since the start, we have needed to add people here and there and teach brand new folks the whole lever duties etc but all in all is not hard once the strategy is understood by the entirety of the raid.
