yeah do it yourself or stop moaning and just don't use it. Giving suggestions/critics is different than rejecting something at all nitpicking over minimal things.
I may understand arguing over the aspect of the nose (a big change indeed), but you are arguing about a couple of turretts placed offset and a minor change in the fov of some of them. I really hope that you are kidding about that, I may agree that the blind spots should remain the same of the original models, if present, but that's up, and this one could be easiliy fixed.
Hell, the gameplay doesn't change when you make modifications, but only if those modifications affect the way you play. You could even change the number of turretts and their position and don't change AT ALL the gameplay if you do it wisely, preserving the same blind spots and the real effectiveness of the defenses.
