There is one option that I have never seen mentioned that would put an end to the VIP vs Premium vs F2P conversations.
Game is F2P for all. No Premium or VIP.
Since there is no subscription revenue coming in, this would mean that everything would have to be purchased for real money. New expansion comes out the only way you can get the content is real money no more getting the content only with DDO point as they can be obtained through playing. Maybe add the option of getting the content only part with Astral Shards, which can only be obtained with real money.
Otto's boxes, bank/inventory, character slots, races/iconics and the like, real money or AS.
Basically DDO points would be good for hirelings, augments, cosmetics, tools/picks basically the odds and ends.
This could quite possibly turn into a higher revenue stream than the current model.
Of course those that have a dragon's horde worth of DDO point will be getting the shaft but hey everybody would have the same account level and abilities.
