A number of questions within the survey ask about the satisfaction with Battle Rifles in general, including all Battle Rifles within this category, inclusding the G3, EBR, Mk17, SVD and FAL. However, I think that this does not accurately capture the issue within Battle Rifles, since the problem with these weapons is largely down to 2 weapons; the FAL (due to it's damage and wide availability) and the SVD (due to it's abundance and damage).
In general the issues with Battle Rifles (i.e. the FAL and the G3) come about because of their combination of wide availability and their controllable recoil. These weapons are already quite controllable on full auto as is, but their recoil is reduced to a trivial inconvenience (especially in light of their damage) by the addition of a foregrip, which reduces their recoil to the levels of assault rifles.
This makes high damage Battle Rifles too good as weapons, since they allow for high damage, high accuracy and their main real life drawback can be practically eliminated by the addition of a foregrip.
I would therefore like to suggest either increasing their recoil or nerfing the foregrip attachment for them, since this attachment basically negates their drawbacks and makes them into meta weapons.
