Guild Wars 2

I am aware of all the trouble that goes into making a balanced map for three forces. Anet has done a wonderful job on the WvW maps, however, things gets a bit boring after a while. So here is my (somewhat simplish) suggestion if they lack the manpower to balance everything perfectly:

Keep the same map design, but change the skins. That way you don’t have to worry about balancing them, while at the same time giving the players at least some varying graphics. Maybe even tiny changes.

For example, the current map set feels very krytan in spirit. Why not make an ascalonian one with a charr feel to it? With tar elementals and deserts, and lava and those lovely autumn forests. Maybe ghosts instead of quaggans.

There could be a maguuma jungle asura/sylvari set, heavily overgrown and with actual forests that hinder LoS and spiders everywhere. A golem laboratory instead of the quaggans.

There could be a shiverpeaks inspired snow map, with kodan mercenaries and polar bears and a lake that is semi-frozen.

Every week you could have a random theme for either of the maps, 3 for each border, 1 for the EB. That way things would be visually more interesting. If you want to, you can have it on a strict rotation. For example:

Week 1: EB: Kryta, Blue: Ascalon. Green: Maguuma, Red: Shiverpeaks
Week 2: EB: Ascalon, Blue: Maguuma, Green: Shiverpeaks, Red: Kryta
and so on.

That way, even if the tiers are frozen, at least the home map will vary.
