Because you wouldn't believe the messages from players I get asking where they can get it. And that is worth the horrendous look. Also, consider the value of the item should it be discontinued, if you can get a full set of Queen's Guard gear that levels you to 31, but you can't obtain it through normal play means, what does that for value? It drives it up. Look at God Armor in Runescape, you can't obtain it through normal means anymore, so you have to buy it, and it's not cheap.
