I think the long term health of faf as a community would be greatly helped by a system of dealing with laggers. I can only imagine the frustration of new players if their early games all have laggers in them. I'd be surprised if they didn't assume that FAF was not worth playing as a result.
We need a system to enable us, as a community, to flag players that cause issues. Flagged players can then be educated in how to improve their setup or maybe put in a pool of similar players.
It's insane to me that in a 12 player game for example if there is even one lagger then 11 other people have to have their fun spoiled. You just don't get that in real life, you'd move away from such selfish people, whereas in FAF I cannot.
At the very least, as an absolute starting point, if every player (including myself obviously) could see how many times they have been set as FOE that would be eye-opening...!
