Talked to a group of old guildies last night who had formed a guild about two years ago. Great players and are top 200-250-ish US consistently while having a pretty minimal raid schedule. But it seems their retail guild is having issues with attendance issues due to burnout from Classic WoW. Half of their officer core would rather play/raid in classic then retail and members are not logging in during their retail raid times causing major attendance issues. And their recruitment officer just told them that he'd rather just play Classic now.
Is this happening to any other retail guilds you're in?
