But that's the beautiful part. Rewards are like trophies. You work hard for them, and there's a chance you might not even get it. Back in BC I used to love to look at players with the legendary warglaives, I knew I was never going to get them, but it was somewhat magical to know that a group of players decided to venture into a dark and dificult raid and ended victorious. The magic lies within the story, the challange, the glory behind the item. Also, they don't tend to remove the mounts (they even reimplemented the naxx10 achieve mount) so you could always try and farm it next expansion, hell if you really want it this expansion you can even buy yourself a spot in a raid. I just got Al'ar a few weeks ago and I don't feel "cheated" by Blizzard.
