Actually this is something you paid for... if you look at the $5 extra fee you paid in your preorder it includes early access time with that crystal you get in game to modify the color of your weapon (lightsaber, blaster bolts....)
I am not QQing about not getting in right away as its now the 15th when they said the early access invites would begin and I've had quite a few laughs at the people who are ************ because they haven't gotten the extra 2 days. I look forward to recieving my invite and playing but am not expecting to be in right away since I was a late pre order person.
