Counterpoint - Beastlords in raid guilds that have reached this level should not be getting hit much whereas Monks still pull certain encounters. Therefore the monk would need Avoidance much more than the BL.
That being said I hate these "which class should get the item" debates. Just making the point that you can usually argue for any class and make some valid points. Each guild decides in it's own way. <shrug>
I'm a monk and would put in to loot this item. If it went to a guild BL first then I would lsap him on the back and say congrats! Every upgrade to an individual member's equipment helps the guild as a whole.
