Don't know if someone already suggested this because Lemuria has been out for awhile.
I think in the crown shop they should add at least two new fountains. A health fountain and a mana fountain. One fountain gives health whisps and another gives mana whisps. In Sky City, Lumeria beside the "Neighborhood Watch" recipe vendor is a mana fountain. I think it's always a drag to go to other worlds for mana and health because other worlds don't have both in their main commons area.
I would think they could be priced like so: Mana Fountain: 1,500 Crowns Health Fountain: 1,500 Crowns Health and Mana Fountain: 3,000 Crowns
I think especially for guilds and houses that have gauntlets.
