Earning RP while Playing

OK so I had an awesome way for riot to make some easy cash and for everyone to earn RP if they play together. Make a new player boost that lasts for a day. A person spends $10 to get it. The boost will Allow that person to then earn RP every game per 1/2 of the amount of IP earned. So this would force people who wanted to buy this to either play all day to make the $10 worth it. or to play as a party. This is where it gets better. If you play in a group the player boost you get for being in a party would allow for you to earn RP at still the 1/2 IP but include the player party boost.

So if you were on your own and you earned 100 IP you would receive 50 RP for that match but if you were in a 5 man party and earned 400 IP you would earn 200 RP. This way those who played a lot and in big groups would have a even bigger incentive to play together. But if RIOT thinks it would not give them extra cash from the people who are winning all the RP. Think about all the people who will spend $10 and not earn 1000 RP. That way only the dedicated people could get an easy ride to cool new skins and others will blow their money on a quick boost.

To make this an even harder goal, a rule could be applied that the boost would only apply for ranked games. That way only dedicated players would use it but it would give more people a fun incentive to play ranked. There all lots of good people who don't bother with ranked and this would definitely boost the numbers a little for sure.

Feel free to comment. was just a random idea to make a cool new way to earn RP while getting your buddies to play in groups when they just want to be boring :)
