Is it okay to use another player's character 'fantasia' as your own without asking?

What they mean is seeing someone with a look they like then using that same look for thier character. They don't mean actually using someone else's Fantasia vial.

I don't think there is anything wrong with it.

I mean this. Say you see someone's character you like, and go "OMG they look so good" then log out to recreate them for yourself to use.
