1. I say no. RoPs are meant to be exclusive, only available for purchase during the small period that it was available for donation. The limited amount we have is what makes the economy for them.
2. No again.. this would pretty much ruin the economy of our belts, virtually making every belt cost the same. Unless of course this NPC charges a substantial amount.. (25?) but even then I would think that this is just a waste of time.
3. I don't think it should, but it did come with that huge official update which has caused a multitude of changes. But if anything, I do agree with having it changed to not penetrating it anymore.
