I guess I'm trying to say that "lone wolf ffa" is not humanly possible, simply because we're not CAI. We can see beyond simple numbers. If we're in a FFA, I am aware of who you are and what I think my chances are against you. Even if I didn't mean to, I will take the chance to jump on you directly or not jump on a neighbor that is targeting you if either serve my purpose.
CAI on the other hand is the only true lone wolf and they just attack what they think is the weakest position. In fact, CAI specifically is what board game players would call kingmaker. All the participants gang on the weakest, one is made strong in the process who is then further not targeted by the remaining participants. The stronger the king becomes, the less he is targeted and the more others fight among themselves. I don't think players would ever behave this way unless they lack so much information they effectively play blind to anything but their direct neighbors (see ramparts).
I guess what I'm really saying is I, even if unintentionally, play diplomacy. I just prefer to engage in it as little as possible and don't wish for any system to be added on top of it.
I think fully muting a FFA match plays to kingmaker. If you can't truthfully declare a player controls significantly more resources than the pack, you end up acting like CAI. The only way to not play kingmaker is to make sure all players have as much vision as possible at all times and make rational decisions.
