Edit: updated thread title and merged threads
The reason why you only got skins from the season pass is because the DLC characters haven't been released yet. The season pass is essentially a pre-order with bonus skins.
Also, under each post is a 'reply' button which opens another window from which you will see a 'quote' button. It would make it a lot easier to see who you're replying to.
