there are far too many factors that make team matchup an issue to get rid of it now, such as the relative lack of spinners that can do much vs stall (other than trick ring target starmie and subtoxic tentacruel, one of which is a gimmick and the other only works on rain), the presence of trappers that can make you play conservatively with ttar/hippo/toed/tales/tran/skarm, etc. none of these are, in my mind, broken.
