The FIA faction has a detailed overview of the ownership and locations of the various bases.
This seems to lead to a form of "legal" cheating.
I have encountered several teams that have one or two guys playing as FIA agents, while the rest belong to one of the standard factions (in fact, most of the time that were russian teams but this doesn't matter). This gives such a "mixed team" an improper, unfair informational advantage regarding the location of enemy bases; furthermore, it makes it easy and quick to deduce where the opposing main base is located (even—or especially—at the start of a match). In my view, this borders on cheating, or is at least a more-or-less legal but unfair way of gaining an huge knowledge advantage in comparison to the opposing faction.
