As for the ongoing debate for hip shooting I suggest it only be allowed when you are surprised by a enemy at close range such as in a building or trench, as this is where it will be most likely be used during real world situations. ( Sidearm hip shooting is taught to the military and police but only from a distance of 3 yards. as a defensive tactic, as a side arm is considered a defensive weapon not offensive ) Shooting from the hip use to be taught for long guns in a close walking frontal assault, but only with the intent of keeping the enemy down behind cover, (as hip shooting is inaccurate and only waste ammo), but that tactic is suicidal in most cases, and is not taught ( in the US ) any longer.
The one life issue I feel is a valid realism concept but only during match or scrim play. Other than that it takes the fun out of the game, and who wants to sit and wait for a round to finish during non match/scrim play !
The following is just a bit of real world information, and is not intended as a suggested requirement for RO TR.
CQB ( Close Quarters Battle ) weapons handling techniques are taught for MOUT ( Military Operations on Urban Terrain ) in most cases by employing the weapon from the shoulder while walking and looking just above/over the sights , and the same above/over the sight technique applies to the sidearm also. ( Also where the weapon moves, the head moves also, at such close range point of aim is point of impact. ) CQB, MOUT is also taught to not only the Military but also to all US Police units not just SWAT.
Another area for TR consideration I feel should be addressed is the manning of tanks during match/scrim play. All tanks should be manned by a full crew as it would be in real world scenarios.
