In addition to purchasing an MMR reset you should be able to purchase blocks of MMR for example +25/50/100 MMR. This could be limited to x number of purchases over a period of time to prevent abuse.
the only person that voted yes on this are you - this idea would ruin the gameplay in any bracket above 1500 and mmr is not there to represent the size of your penis online - its an indicator in which bracket you belong (skillwise) to make even and balanced games
My Suggestion - Coin History:
The simple answer to that would be to only allow it below 1500. If a full reset to 1500 is fine why not allow someone boost by a smaller amount rather than fill the 1500 bracket with new players + reset players?
This is a terrible suggestion. The ENTIRE purpose OF MMR is to measure a players skill... If you can just buy your way to higher MMR is completely destroys the system. Down voted.
Why would you pay for MMR? A player that doesnt belong in that bracket will be the centre of a shitstorm. Overall, terrible idea.
