Finished Faction's, What next?

alas! Ive finished the main mission on factions campaign! but im not sure what to do next?

So you beat Shiro, right? If so you can

- go do the missions for the other side. If you went the Kurzick route do the Luxon missions, or vice versa.

- pursue a title, Protector of Cantha or whatever

- cap elites

- hunt bosses (farm)

- do challenge missions

- do alliance battles

- start another toon

- do PvP

- add Prophecies or Nightfall to your account
