I actually mentioned this in another “map design” thread as a great idea. There are really two ways to make small group play more viable, and zerg gameplay less viable, that is to either make the maps much larger, allowing room for small, quick groups to outmaneuver zergs, or create relatively small, but complex maps that would accomplish effectively the same thing. My personal prefference would be an urban map, because first of all, it rewards experienced players who really learn the lay of the land and learn how to use the terrain to their advantage, and it also removes one of the problems of huge maps: travel time.
There were a number of complaints back in beta about how large WvW maps were, and how annoying it was to have to run back and forth between objectives, and how players were spending more time running to battles than actually fighting in them. Now, today, i don’t know of a single dedicated WvWer who still thinks that the maps are too big, but this could become a problem if maps become too huge.
Although I definitely consider the current maps to be too small, the main problem with the current maps is in their setup, there is generally only one good way to get from point A to point B on the current maps, encouraging no variation. An urban map with side streets, alleyways, and multiple roads to any particular destination would be absolutely ideal.
