What the title says:
in order to reduce the work load of creating new maps, but off course shiny new unseen before maps are good too, in order to reduce the work load and to maximise your existing assets. i suggest adopting pve map for WvW , off course the normal pve maps still running, find a section of the pve map each week for wvw fights in another server instance, players will enter the instance like Living story would, you find the portal and enters from there and fight for your guild to hold the land.
pros of adopting pve maps for WvW,
1) potentially inviting more pve players to participate in wvw, as it is their familiar terrain, enters thru pve map.
2) dynamic impact on the tyrian world map to boost Guild Particiaption. as the world map will show who is winning where everyone can see.
Everyone is welcome to discuss.
