Started a new arena team yesterday.
2v2 Team - Rating 1675
Personal Rating 1669 [ 27 Wins - 18 Loses (66% Win Ratio) ]
Now I looked at another person on the server, found this
2v2 Team - Rating 1785
Personal Rating (of person in question) 1780 [ 53 wins - 48 loses (52% Win Raio) ]
So my question is, does your win ratio not factor in at all into your personal rating, it's just a matter of how many games you've played and won ?
