That's very unfortunate, but this suggestion can't and most likely will never be feasible. If this were to succeed, then the Fallen Nihil outfit would also have to be made available again and possibly a bunch of other things as well! Really, this would just create a massive snowball!
Honestly, I know the posters above aren't going to agree with me but sure i support. It's not anything important or stated as exclusive and if Jagex can make more money by putting it up on SGS then, why not. Support.
