Meganoide: Don't forget Brook or Usopp, since both of their jobs are optional, they can count as "useless" members too. Just saying.

On-topic: 2 more is enough. Currently the only one I can see joining at this point is Marguerite. And since all the job spots of a pirate crew are now filled in the Straw Hats (unless Oda shows us otherwise,optional or not) she would become another additional "useless" member. The only job left for her,based on her fighting skill from what we seen, could be like Usopp, a Marksman. Or Markswoman if you prefer it. lol

As for who the final one could be, no idea. Someone from Fishman Island or New World.
