First of all.
1. Please add option to queue for all battlegrounds at once. On Far Shiverpeaks which is really crowded EU server it’s hard to get into single map. At this point, I don’t care which map i get i just want to be in.
Now gameplay suggestion.
1. On WvW there should be resource generation outposts. These outpost would generate gold, karma, experience for players who control them.
2. Those generated resources must be transported to your main keep. on map. Only when caravan reaches an keep, players get generated resources.
3. To make things even more interesting, mines (short for resource generation outpost), would be linked to closest keep. If you want to control them, you must control keep. If you loose control over keep, you do not automatically loose control over mines. Enemy must take them one by one.
So while is not possible to take mines without taking keep, it’s still possible to block enemy resources by killing caravans.
Another idea is special ability called hm “Call Caravan”. When you kill enemy transport, it’s possible to summon your own transport that will take enemy resources and start transporting them for your faction. To not make things to easy, your own caravan will spawn in closest controlled outpost/keep and start travel from there.
