Let's not forget that compared to the smg's it's still not as good though. If almost one whole category of guns is better than the FAL then I don't think that it is overpowered in the slightest.
You must be kidding. The best SMG (MSMC) is very comparable to the very first assault rifle (MTAR), which is extremely average. When the first assault rifle outclasses every other SMG, how can you say SMGs are objectively better than the FAL OSW, which is a top-three assault rifle regardless of whose list you cite.
