Draken jets has only 20min of fuel and Gaijin since first drop fuel tanks didnt gave Draken their fuel tanks which would help them a lot. On J35D i also notice that it still doesnt have option of a cutom load out and i thing it would be nice to have it. Plus the gun aiming assist like we can see on JA37D because unless you handle the balistic of the guns, you need to get really close to the enemy jet to hit your shots.
Plus maybe it would be nice to see a CAS version of Draken that had a better payload then AJS37 have now…so yeah…lets hope and cope we will see these things one day.
