RP rollover

So this is kind of an idea-rant situation. I can't tell you how many times I've had to purchase rp when I am just 40-50 short and end up having to spend another 5 dollars on something when I just spent 10. So I think I have come up with a solution, make the rp cost $.10. If you do the math, its about what it comes out to. for example, a champ thats 987 rp it comes out to 9.87 and you have to spend at least 10 bucks to buy it anyway. I would much rather just pay for the riot points that I'm short on rather than have to buy another 680 rp just to be short again later on down the road. I know riot is a business and thats capitalism but I've spent a TON of needless money. I mean I doubt this will even get noticed but I think you would be doing all of your customers and players a good service.
