Actually, there have been some where non-combatants have been able to get in on with all the different roles that exist. For instance, Haruhi and Azusa aren't really combatants and they have gone, so at least there are some roles they can play.
Though that does give me an idea that maybe I should suggest for a unique mission. Basically something that seems ordinary and mundane and really about any character could probably pull it off. Maybe it even is done like the normal missions and doesn't appear special to the characters at all but it is OOCly signed up for as a unique mission. But said mission ends up being ambushed by the Third Party and those who go end up seriously injured and/or dead. Or they could get a rescue from other characters or the Malnosso security forces. Could be interesting, and I could see players being willing to sign up even knowing their character would die.
