Every zone in the game becomes part of a weekly rotation of several zones that become PVE-PVP hot spots.
Smaller settlements and areas will get some small barracks/outposts that temporarily show up, where players get points to defend that area and enemy players get points for attacking that area. There are daily quests that pop up too.
In game now, a group of players can go attack the NPCs and players at a hub and kill the Flightmaster. When this happens, the opposing faction’s players will form groups to go and protect that area and let the Flightmaster NPC reload and take their rightful place, allowing more to fly to that location. Players who are organized can attack multiple hubs in each zone, taking away access to FPs around the entire zone and that leads to amazing open world PVP battles.
So what if we took that and boosted it to include quests and some extra assets and make it a system that can happen anywhere across all zones in the game. A good way to start is by doing it in all the azeroth zones. This could be a way to get players to work on objectives together and have pve and pvp fun in zones they might have already completed the content in.
Just an idea. The great thing is if you get players from both factions to do more of this, we could have whole zones locked down until players group up and retake those hubs. I have been a part of this type of activity many times. No matter what xpac and no matter if you have completed every bit of content in the game, this will always be something that the players can do and get a lot more use from the gameworld.
