Hi, with all change planed to the wvw i think it's the good day (or not ) to post this.
One simple and easy change in wvw.
Take the "Obsidian sanctum" map.
Remove this map of the actual matchup like the edge of the mist.
Add map instances selections for everyone.
Result, you clic on the "obsidian sanctum" then you can select:
map 1 red
map 1 blue
map 1 green
map 2 red
map 2 blue
I don't know if this map is active or not, but probably 3 instance of the map is enouth to let people who whant to duel gvg ect have fun on this map.
