I agree that across the board DCS needs to move away from dice roll for counter measures. I think big picture the EW environment needs to be improved (Hornet, Viper and Tomcat are immune to jammers), RWR picture is too good across the board and TWS is widely used in the NATO jets: any pilot would tell you that they wouldn't rely on TWS the way it is in DCS.
If the above gets addressed the gap would close a bit.
