Left over IP

I don't know if this has been an idea or not but, I finally purchased the last rune possible for my account and now my ip has just been sitting there collecting dust. I think their should be an icon something that costs like 100k ip for us to get to make use of the in game money. I know when new characters come out we can use some of it but they only come out once every 3 months or so. which makes it really easy to have well over that amount.
