Honestly, these topics are useless. Bungie has already said they weren't going to do it, and they have no obligation to do so. You chose to play the beta, which is merely meant to test. Never was there any indication that progress would carry over. Everyone is going to lose stuff, but so what? If you enjoyed the game, replaying the missions should not be that big of a deal. The full game is going to have less accelerated leveling (something put in for the Beta), and many things are likely to be different. Thus, there is no point in asking for this, it isn't happening.
