I've been looking around to figure out exactly what I would gain/lose by subbing for one month then downgrading back to Premium. From what I found so far I know that downgrading from VIP to Premium ...
2 Extra Bag Slots
Gold Cap removal
Riding Skill (if trained during VIP)
PvMP (at least until Isengard)
Extra Character Slots
Access to yet-un-purchased quest packs
So, given that (which I hope and assume is accurate so far) I have a few questions for those that have downgraded from VIP to Premium.
For Trait slots, do you permanently unlock all Trait Slots on your current characters or only the ones you have already unlocked via level? For example, say I have a level 21 character who currently is Premium with 1 TP-locked Virtue slot and 3 level-locked Virtue slots. When I upgrade to VIP, I will unlock the TP-locked slot immediately. If I downgrade to Premium before unlocking the last 3 level-locked slots by leveling, will I have to unlock them with TPs or will they be available as soon as I level up?
For the Wardrobe, Premium does not have access to the Wardrobe (without unlocking it with TP) but VIPs get the first 10 slots. If I downgrade to Premium, do I still get these 10 slots or does the Wardrobe go back to being unlocked via TP?
For Crafting Guilds, I heard that Premium must unlock Crafting Guild reputations beyond Acquaintance standing via TP but VIPs have no such limit. If I downgrade from VIP to Premium, does that unlock stay? Do I need to be a member of the Crafting Guild prior to downgrading? Do I need to get my reputation beyond that standing first?
