I am new to the forums, so I do not not know if this has been suggested (though I did see the IP to RP suggestion and that doesn't make sense to me -_-). Question for all: Have you ever had around 50-150 RP left and there is NOTHING cheap enough to buy with said meager amount?
What about being able to convert leftover RP into IP via a set exchange rate instead? I don't see how this could hurt them or anything financially, but feel free to provide a point that I may have missed. Also, if this is already a feature I somehow miraculously missed, I apologize for wasting your time.
