"Players will begin receiving rewards based on the above requirements with the release of patch 4.1. Those who have yet to obtain these rewards but already meet the requirements will receive them shortly after the update. (For example: A player with 330 subscription days on their account will meet the requirements for Rank 4, and thus receive the Leonhart Attire reward.)"

So I have Veteran Rank 1 in my account and I have NOT received the Advent Attire. I'd like to know why.
