What bothers me is - with 256 people in a match , people are going to be so spread out on the map, that it just might be another map to those people who are far off! How do I get the feel that all the players are in this map I am playing, when half of them are 10 kms away!
No no, on the contrary - that's what's going to make it awesome. I can very well see a situation in which once a squad has completed it's targeted objectives, they are to rendezvous with another squad at a certain larger objective... maybe one side will be on defense, and the other on offense, and both squads will come from different directions. Likewise, if a squad is pinned down elsewhere on the map, it won't be able to join up in order to take part in the second-stage objective.
In my mind, I'm seeing a game where individual squad actions definitely count, and everything in the context of a larger field action/victory.
