As far as I know, there are no member farming quests for Juggernaut items, and there are just the normal quests. My best advice would just to upgrade to max enhancements/best gear, and start botting with all items other then the mana golem items(I assume this is the quest you will be farming) whitelisted.See if that works. I got non-mem Voucher in 3 days using this method. Hope I helped! Please thank me!
