Some very vaild points raised here.
For some strange reason known only to TGC the player behaviour is just about the only thing that a user is given almost no control over at all.
I can only think that this is due to the fact that there is no real player of course and changing settings of camera/weapon/player might have undesirable influence one upon the other.
Putting editable Player functionality and control in the hands of the user as well as other restricted functionality in other areas would be an enviable objective to aim for and in the end analysis would allow better games to be made as a result.
