That might make more sense if my friend who was in the same games only with much worse stats and by her own admision is a much worse and highly inconsistant player had not been promoted to Bronze division rather quickly. That's the part that doesn't make sense, if she also had not been promoted yet then it'd make a lot more sense and I'd have never thought much about it.
Could it jsut be that the sub-group I was placed into is a much tougher group considering how much stronger I play than her?
