MachFly, let me ask you this question:
Do you shut off your engine in combat as a standard "ACM"?
If not... then let me ask you this:
Why are you so assertive that this shouldn't be changed?
No I don't because it's stupid and mos likely wont help me. The reason I don't want this changed is because I don't have a problem with people doing stupid things that cause them to loose in the end. Another reason why I don't want this changed is because you could do the same in real life.
For example we have people in AH who always do belly landings, they don't care about the plane and it's easier for them to do that. In real life if you do that you'll damage the plane so you don't do a belly landing every time.
Also I can't think of a realistic way to stop people from turning off their engines in flight without adding random malfunctions, and trust me were better off with some people turning their engines off and on than all of us randomly loosing engines.
See I understand why your asking for this but I just don't see an effective solution. Plus I don't think that this is a big problem.
