The problem with the FAL as it stands is that it's a 1 shot kill on light armour while other weapons in the general pool (available to the Demo, Rifleman, Commander and Observer classes) in and around its caliber are all 2 shot kills (this seems to be the only AR/BR within the general weapons pool to be able to do so). While I understand that this may be due to its higher muzzle velocity, it creates a problem in terms of gameplay since it elevates the FAL above its peers (such as the G3) by virtue of its damage and makes it a superior choice to what should be its alternative.
This creates a problem within the Battle Rifle category, since the G3 and FAL are no longer alternatives, the FAL does appreciably more damage. Furthermore, in the present case, the greater muzzle velocity is already a buff in and of itself without adding in greater damage on top due to lesser travel time and a greater hitscan range.
Therefore, I would like to suggest that the FAL's damage profile be rationalised by bringing it in line with other battle rifles in its caliber such as the G3 and SCAR H. This would allow the G3 and FAL to remain viable alternatives of each other instead of inordinately elevating the FAL by virtue of better damage.
