I actually agree on disabling rank requirements for mods.
What of most disgusting things I saw in-games are finals of missions with one team being under R195 overall and second being R195 or above. They usually pack item or themselves into car, one takes car surfer and OSMAW/OPGL or LMG and proceed to defend car while opposition without this mods are pretty much struggling to get objective/kill targets.
Thankfully I though of some good counter-strategy which I will share to some under R195 which are struggling. Whenever something like that happens, passanger should pick up DMR or ISSR-B (better but ARMAs option) and shot down car surfer - both weapons you can use while peeking outside windows and they have huge car damage (and can deal with opponents out in open pretty quick too, with no misses it should easily outshot OSMAW), so after eliminating car surfer, proceed to shot car - it will quickly burst in flames, make sure driver or other passangers are prepared with weapons they feel the best with... take over item and run away too with such equipped passanger (I mean, they did that - you have full right to do it too).
You just won game, congratulations.
