Well this could be solved by making it so that using animas ONLY teleports yourself so that would fix 2 issues:
1- you cannot be teleported to places you never visited since you can only teleport yourself.
2- people cannot "abuse" the system by making mule and teleport their other chars without consequences.
There I fixed it
Edit: and of course they can then introduce teleport spells to white mage or better yet time mage to be able to teleport the whole group.
Anima's = solo convenient transportation system
Spells = party play transportation
and you have choco, boats, airship, etc, to add on to that.
