roads would be a great addition
but what i really hope they will add is some good pathfinding for the parties on the map, as of now parties usually take the "line of sight" direction to reach theirs destination and then needs to change it because of natural obstacles, or get slowed by terrain malus even if there's a clear path with good terrain to reach the same destination, both behaviours are annoying and make parties travel for more time than needed (so more risk to be attacked)
This is a major change from the M&B and Warband map, where the "roads" would override pathfinding for any distance greater than about 3-4 seconds' travel on the world map. No matter that the road was in the wrong direction, your party would go 120 or 150 degrees out of its way to reach the nearest road ("We MUST follow the road"), and THEN calculate a path to the destination, which was now further away than when you first clicked. The roads offered no actual speed bonus, and worse, usually led directly through woods or other difficult terrain, making following the roads generally SLOWER than traveling overland. In a number of cases, my party reversed course completely to go BACK to a road that was 180 degrees out of their way. In at least 2 cases, that took them straight back into a pursuing army. I learned that you MUST click close to your party, repeatedly, to avoid them trying to find a road. This has been the cause of a significant increase in tedium for me. Why should you be able to click just once when the game can make you click 20-30 times to accomplish the same thing a lot faster, right? The real annoyance was that 99% of the "roads" were invisible, but affected path-finding anywhere in their vicinity.
Roads are a good idea in theory, but:
A - they should provide a slight speed bonus.
B - they should be plainly visible.
C - they should ONLY run between major towns and castles, from those directly to their attached villages, or to other points of significant interest.
D - your party should never deviate more than 45 degrees out of its way to reach a road (otherwise the road would likely make the trip take longer).
E - roads should either negate some terrain penalties, and possibly reduce night movement penalties as well, or else be routed mainly through clear terrain. Nobody is going to build a road that takes LONGER to use than traveling directly cross-country, and I can't picture any player wanting that either.
