I don't think cheating is much of an issue in bf. There's probably a ton of the recoil macros, but actual hacks like aimbot / walls aren't really present in bf. I also think its by design the lis can't two tap all the armored vehicles. It's a war game, not a rambo game. I think it would also improve your score and skill to play with people on comms or play regularly with the same friends. One solid squad can run the whole map really.
Unless you are on the Asian servers I'm skeptical of any rampant cheating claims. I've played a lot and just haven't seen it.
Lis probably shouldn't be able to solo tanks at range with just the G84.. Her speciality is anti-air and extreme range chip damage. You can still run her with G84 + C5 + AP under barrel nades if your goal is to solo tanks.
