Only 3% of the player-base owns the Brutosaur mount, the greater majority of you that are outraged were never going to buy it anyway. You’ve had nearly this whole expansion and still have over a year to buy this mount if you want it that bad. Most players have never seen 5 million gold, yet alone will ever have enough gold at one time to ever think about purchasing this mount in the first place. TCG mounts have been around for many, many years and the vast majority of players have never had enough gold to ever even buy one of them.
This is just the next topic for players to be outraged about instead of focusing on the real issues of the game.
