They can change the way the system work. Not able to use custom text, only a drop down list of pre-defined sentences etc.
Create a listing, choose your dungeon and key level or raid/bosses. And thats the title of the listing. And then drop down menus for everything else. classes you need/want, bosses you are going for/have killed etc. There is no reason to have custom text. Players would quickly adapt to this and there would be no way to advertise
