The thing is you need to 'attune' before you teleport somewhere. The FC gives you buffs, because you're attuned with your free company. Other people can not be attuned to your crystal/FC buffs, because they are not part of your group.


And do you mean like a 'Best In Slot' button for your class? I don't see how it'd fully work if you don't have space in your armory chest.
