Regarding PvP, the team recently announced some new information about what it will be like. PvP is faction-based; your account will be aligned with one of three factions. The three factions will battle it out in a contested area with a variety of overall objectives. As for endgame, after players finish the storyline, there are a number of challenges that players will face, many of them centering around the idea that all the characters have an ultimate power. Players who finish the storyline (usually around level 30) can unlock this ultimate power by collecting tokens that drop from various bosses. There will be some endgame content that's for smaller, coordinated groups, and then there is content that requires much larger numbers of players, although it's very inclusive in that multiple parties can all participate together and players can jump in at any point.
