If they put in something like signet, it needs to be different so it doesn't come down to remembering to grab it on the way out of town. Maybe make it so there are different kinds of signets that stay on your character at all times, but you can switch between them whenever you want. Or just give everyone a permanent signet that acts differently depending on which region you are sided with. The fact that they removed shell and combined the effects with protect already goes against the idea of bothering with a signet like ff11s. It either needs to be permanent or there needs to be a downside or gamble for using it otherwise it won't add anything meaningful.
