As for favoring the better pilot, there are a lot of different kinds of better pilots. Some shoot better, some fly better and others prepare better. The first two kinds of pilot are already able to show their skill in IL2. What will change by including realistic systems modelling is that it will enable the third kind of pilots to do the same
I don't know if SoW will include all that. However, i have a feeling it will be able to include them in the future. We didn't have perfect mode, water=3 and radio navigation in IL2 either back in 2001, but we have the first two now and we're about to get the third one thanks to team daidalos (just to gently steer the discussion back on topic )
