Thank you! I think we might be already over-level for Alderaan. Not sure how.
Have you done every single heroic thus far? Every single flashpoint, plus the daily connected to its level range?
If you have and you're a subscriber, it's not exactly hard to be overleveled at times. I ignore heroics, space missions and flashpoints on my newest characters and I'm always 4+ levels ahead of the target content I'm doing. Don't use XP boosts neither but have tons of rested XP though.
