There is absolutely no need for this. I hear people saying that it will keep the crafters going but that is what the materia system is for. With the materia system people will still constantly be blowing through gear to try and get materia, so there will always be a need for crafters.

Making it to where you cannot sell your used gear is just plain retarded. I really hope SE changes it because in my opinion there is no point. Crafting was very essential in 1.0 and it would be the same in 2.0 without this stupid binding feature. If anything this will make the market or AH pretty lame imho.
