No. No way. It does NOT take hardcore playtime to cap out everything you can do at 50. As a matter of fact, Datacrons are the most time consuming thing you can do, and that most of the time literally means walking around barren lifeless planets or waiting 2 hours for a balloon to roll by.
Yeah, awesome gameplay. Totally worth the 60 dollar price tag. Wait, i can pay you 15 bucks a month as well for no reason? Awesome!
