I pre-ordered in July and Amazon didn't send me my code until October when I bugged em about it. I didn't even know I'd need the pre-order code for the beta or the early access.
That's what bums me out about it most. The whole process was pretty confusing for me.
Anyway, I'm glad I was able to get in at least one beta weekend, so when I eventually get in, I'll skip through all the dialogue and hopefully catch up to my guildmates.
