Lusche has no skin in the game, and doesn't skew his numbers. Yes, there are other evaluations on 'score' in this game such as k/h, but again, it doesn't change the fact that NOTHING HAS CHANGED by the numbers. It's the PERCEPTION of people thinking they are being singled out.
If you want to look at something REAL that changed in the game due to a change in mechanics, look at the A2A kills of the IL2 once F3 was removed. There is a very real disconnect in what happened/was happening there and the game fixed it.
Fact of the matter is, even with GV dar, it's still nearly impossible to see a GV until it's too late. The statistics in this regard show no real difference in this. I think the real telling numbers would be the amount of A2G kills prior to icon range being shortened, A2G kills prior to the Storch being put in and range being shortened even more, and AH3 where vehicles are mostly invisible. I don't have the time or the wont to do the research on this, but I can tell you from my own personal perspective, attack/bomb****ing went way down after all three of those things.
If you want to look at it historically, Trinity was the GV map. V85 spawn was an amazing crapshoot of spawn campers, smoke throwers, CV's shelling/upping attack planes and lancstukkas. This continued through all of the changes up until the map was retired... That being said, If you're red, I'm going to kill you regardless of what your where you are, and I don't need no GV dar to do it (and I still love shooting down buffs in my IL2 if I guessed wrong).
