Couple of things, first Im not claiming "much improved gameplay", and second I dont know what you mean by "you and your crew".
I already said I would like to do an experiment, but again its not currently allowed to add a crosshair overlay, static center dot or not.
So all we can do is discuss. All I am saying is having a center dot is better than guessing where your center is. Might not be a big difference, but it would be different.
