well, it's to be expected -- the cast has expanded and they need their time. post-w7 you have what, thriller bark (lol filler bark am i rite), sabaody archipelago (plot heavy), and then THE AMAZING ADVENTURES OF LUFFY AND NO-ONE ELSE IN AMAZON LILY AND IMPEL DOWN AND MARINEFORD. not much room for nami -- or any other character that isn't brooke -- to shine! post-w7 has been basically picking up brooke and then moving events in the world along, rather than NAKAMA WACKY TIME. (which is sorely missed, actually.)
