Allow a mage class to get spell to teleport to each main camp then you allow to teleport to the sub camp. This give more reason to have a mage in your party beside healing. You still need anima to be allow to teleport to the sub teleport from each main one.
For the craft allow them to teleport to the camp if they have the leves and they use up the anima .
Guildleves: Need to go to camp A
"Teleport A you reach camp A
This way you still need a mage to teleport your party to a guildleves but for the craft they give you the teleport as long as you have the anima for it. Or you can ask a mage to teleport you there if you out of anima.
It's a win win for both.
