Mass coordination is unlikely. Squad hopping until you find a group that satisfies your needs should be enough to ensure a good time. Worked well enough in BF2. Co-op ing nicely with even one random player can make games like this a really pleasing experience. Less restrictive rules the better IMO, just focus on quality map design, like the aforementioned Strike at Karkand. Spawn camping needs to go though, but only for uncappable points or last flag situations. Players having a good time is most important.
