There are other aspects of leveling up besides planet questing. Do your Space mission daily's as well as Flashpoints and Heroics. If nothing else grind on warzones, you'll need all the valor you can get

That's whats i'm starting to think, there going by code redemption date, but also just throwing a couple of random invites as well

Same thing happened to me, I preordered on 7/21 but forgot to redeem the code untill last week, I FEEL YOUR PAIN
