Been so long since i play'd on live i cant think of any. What dose come to mind is the class trainers, if your not of the right class they tell ya that. That is not in a QST file tho and i dont have the experience to be able to track down where that is.
What we are trying to do is have a NPC hand out Kael Armor and epics as starting gear, i curently have it written for 15 NPC's 1 per class, I was hoping of a way to cut it down to one NPC who hands out gear to all classes but only offers you your classes armor. If its not fesable at this time no biggy, would have been nice for looks
