I'm the first person to ever offer a Fun Run boosting service, which will help you go up in rankings and get some coins on the side as well.
Here's a youtube video of it in action:
Currently I'm selling 30 consecutive wins (there is always a chance of dcing but its VERY rare) for $10.
This includes no deaths, a random number of kills each match and:
30x15 rating = 450 rating
30x30 coins = 900 coins
If interested PM me and we'll get started.
