Rhoswen's business gets some more focus in the Lvl 50-60 Cullinarian quests. I do think she and Carvallain are supposed to represent how Limsa Lominsa has changed over the years and how that has effected different types of people in Limsa. Carvallain with his Ishgardian informed upbringing is doing much better under the regulations and limits Limsa now has. Rhoswen with her less structured crew and way of handling things is doing fine, but not outstanding. However, both of them are better off then some of the other pirates we meet in the Arcainist and Rouge's Guild quests.
