Star Rating

The ultimate measure of skill, Star Rating is based off your success in Merc Games, and since success in Merc Games is determined from limiting the failure of your teammates, it is wholly dependant on the randomly given team of 8-9. This is why they call it TrueSkill.

Star rating has been used to insult other players since ancient times, any argument with legimate points can often devolve into "ur x and a x stars so stfu".

There are a few steps you can take to help your Star Rating increase, but they are not guaranteed to work.
