FOV on 2238 has both advantage and disadvantage : it encourages scout use, which is bad, but it allows also fine battles and infiltration attempts. I'm almost sure we'll keep it. Maybe adapt it a bit, dunno what is our scripters' minds. What is modified is the map's configurations. Fallout 2's aren't designed for PvP at all, and even if all don't suck, it's a big part of the problem IMO.
And for scoots, well, there is no definitive system. I personally hope that if scouts exist, they will be true characters of players, and not only created for that purpose.
