Is why I stopped flying competitively, all this stepping up and talking smack.
I find that dueling improves your 1v1ing (obviously) but it doesn't teach you E, SA and changing altitudes. I reckon that the best pilots tend to be the guys you see with 1.5 to 2 KD in the MA, flying regularly.
Its more fun to find yourself in different circumstances and win the fight. When pilots are experienced, it really is a case of circumstance and aircraft type rather than skill.
I can beat Redbull in Spitfires 1v1. Thats it. But in MA, with differing circumstances, Ive killed him while flying a 109. HIS PLANE. Why? circumstance.
