Bingo, game cant hold people becuase:
Replayability is awful (less that 5% content different for each class on same side, group content is mostly the same)
As soon as you hit 50, unless you raid and are gear nut youll quit very soon (more like immediately)
And they wonder why 2+m people said no to SWTOR. What they offer IS NOT worth of subscription, free trial to lvl50 will change nothing.
So, why are you still here?
