2 more dungeons, a shiphand or two (called expeditions now), Arcterra (along with other daily zones), story quests past level 50, a couple solo story dungeons, seasonal/weekend events (most noticable thing since F2P along with Arcterra), and another adventure are the things I can think of off the top of my head. Pretty much all content released since launch has been non-raid focused with the exception of Augmentors, a single boss-in-a-box raid (like Magtheridon or Onyxia in WoW).
