That is very much incorrect. I am not rewarded for playing the game for 6 months. I am rewarded, for signing a contract, that forces me to pay for 6 months. If I don't play for those 6 months, I still get the mount, that's not a reward for playing the game.
The pathfinder mount is fine, I work to get it, by playing the game. The 6 month subscription mount? No.
