i might shift my passing focus if I notice that my opponents CBs are dispossessing my STs often or my wingers are wasting good opportunities with poor crosses, i also look to see if they are playing man marking with trap or zonally. The visual cues in the browser version are quite telling if you know what to look for. i've also been known to flip my strikers/MCs if I am playing two of them, slight changes in arrows can help attackers that are shooting too often wastefully/not enough as well as reduce offsides.
