What are your most played heroes in ranked ? Sides have always been slightly imbalanced , but especially since the big changes to the jungle in recent patches , some heroes are significantly better on one side of the map than on the other , due to fast jungle access or magic damage reduction of some neutral creeps slowing down the farm time of some heroes SF , Lina , QOP and Storm , for instance , come to mind . Either way , this is some serious imbalance in your respective winrates . Of course one could argue that 70 games aren ' t that much to base any speculations on and you might just be a little unlucky this month . But it ' s quite possible that it really is some mixture of preferred heroes , playstyle or simply map side preference .
