I disagree with you Krusty on the FM of the late Il2 series. When I fly IL2 I do have a better feel of flying a real plane than in AH2. The most intense online flying experience also comes from Il2 virtual wars with no icon, no rad map. The bad from IL2 in my opinion is the "fantasy" airplane performances.
Back on topic ...
As far as weathering, those planes flew several sorties a day and were worked on th erest of the time, I have no problem seing such a degradation on the paintjob, granteed not in a mater of days, but definitly in a matter of months. I noticed similar rapid degradations on the cargos planes that we fly in my company. Our plane look already like an oily bucket at the end of a flying week, and a new paint job is already trashed by the end of the month, and looks like it was never painted since factory 6 months later, especially after the winter.
