I wouldn't say it's fair but I feel like it wouldn't really matter to players with Tumblrs. The tumblr could be/would be considered a Dark Below exclusive to players who purchased the Dark Below during the time the tumblr was being offered. while the rest of us who missed out on the deal would have to settle on the "year one sparrow" If anything, wouldn't this increase the value of being one of the players to have a tumblr sparrow? Besides, it's cosmetic. It's not like having the ability to do tricks on your sparrow makes or breaks the game. It might just make things a little more interesting. Note: I don't remember if the tumblr was an incentive attached to the season pass or the dark below, all I know, Is I downloaded it a day after the deal ended :$
