Use for Prestige Points
It's just a suggestion and might confront dislike to some people, mostly those who are already not in good terms with this currency.
But how about giving Prestige Points some additional purpose, as in allowing you to buy past borders (or even bundles including the icons). Some people probably missed the chance and would love to get some of them. Also, right now they're only purpose are prestige skins which are pretty hefty in price, so why not?
