It has A PVP arena, and PVP events as well. I also heard talk of them implementing squad spar arenas soon, so if they can consistently flesh these things out (as in adding more missions, planets, and balancing the leveling system) it can easily stand on its own. You need to take into account how little content iera and iclassic had upon release.
This is very true, both iEra and iClassic started off in the exact same manner.
