I don't understand why people rage because the code is taking a little longer than expected to roll out.
It's not like you can't play the game, as long as you pre-ordered and got into the pre-release.
Everything behind the code (right now) is just cosmetic stuff which has no impact on the gameplay.
I could understand the rage if people couldn't play due to the code being late.
But that's not the case, as of now.
Perhaps people are just bitter that they couldn't be amongst the first to show off the collector items and have their minute of fame. I can't really say.

Anyway, I think people should calm down a little.
From what I've read here it seems the codes are rolling out, slowly but surely.
So they are on the way.

Edit: I don't have my code yet either, so I am just as effected like alot of people are.
