The problem with foregrips is that they practically trivialise the vertical recoil on most guns due to them providing a massive 5-6 points of reduction to vertical recoil.
This becomes especially egregious on Bsttle Rifles such as the FAL, whose one important weakness is easily neutralised by the addition of a foregrip.
This also makes the choice between them and compensators a no brainer in favour of the VFG since the effects of the foregrip are much more palpable and substantial.
IMO this can be solved by toning down the recoil reduction from foregrips to 1-2 points (since a reduction in vertical recoil is also much more palpable than one to horizontal recoil). This would allow foregrips to remain a useful tool, while making them an option rather than the compulsory meta pick.
