Pretty much what this guy said. TOR's development history has sadly been one of consistently cutting corners, scaling back, and providing less and less content with every 'expansion'. The original class/faction stories from 1-50 are still by far the best content and best story in the game, I'm pretty sure the reason they hand out level boosts like candy is because they don't want you to pay attention to that, because then you might realize just how little there really is to KotFE/KotET
