I know, but I didn't get a chance to get more than 2 of a 4 weapon set (titonese, and then the upgrade, got one upgrade and one titonese.) I would of enjoyed finishing the set. I just think it's a loss, an expansion should never REMOVE stuff, just add.
Welcome to MMOs. Items and gear are retired all the time in these games. There are other things along the way that people can no longer get like certain pre-order bonuses or pets. Life goes on.
