dharmacat:I have been cursed lately in alternate shot games with terrible partners within my tier, Master
Sadly we all have bad days on the course, real and on here, well I certainly do!
The only way to acertain their ability is to look at their individual stats before a game - bearing in mind stats can be misleading.
As for A/S I treat these purely as fun, usually with friends and the result really means nothing, just a good laugh. In fact some of the best A/S games I have had in when players play like a hack (including myself lol).
The only stat it will affect is your win/loss record - something I don't even look at personally.
If winning is your priority, play with friends you know.
On a different note you too have been here for a while, level 92 and still a master with very good equipment - some would therefore question your stats. Perhaps you would be better off playing more ranked rounds and concentrating on improving your own game. This is meant without being critical on you but either enjoy A/S for the fun it is or try to be your best so you can win.
