TL;DR: Have a zone in Orr that is like the WvW borderlands maps, with players defending keeps against waves of undead.
A disclaimer first: My highest level character is only 63, so I haven’t seen Orr yet so I don’t know exactly what it’s like in there.
I started playing WvW recently, and I’ve been enjoying the give and take of capturing and defending keeps on a persistent map. Also, I have heard people complain about how in Orr there are too many undead who just mill about, doing nothing. So I was thinking a fun thing to do with Orr would be to create a new zone there with keeps and forts and supply lines like in WvW, but you are fighting against risen instead of other players.
How I imagine it working is that instead of mobs spawning all over the place and mostly staying put, as they do in all other PvE zones, there would be only a few places where they could spawn. But they would spawn in massive amounts there, and flow out to attack the players’ bases. The spawn points should mostly be near the risen’s home base, but have the ability to have large waves rise up from the field anywhere on the map to prevent spawn camping.
The map should mostly work like WvW does: players or undead can assault and take over keeps and supply depots, and have to use supply to upgrade and repair their keeps. Players can build siege weapons to help fight off the undead, but the undead get siege-like mobs that spawn when they have enough supply. Perhaps a monstrous undead beast for a bettering ram, or undead giants that hurl boulders for catapults.
When keeps are being attacked/defended, have dynamic events like in WvW so players can earn xp/money/karma. The difference here being that instead of having a DE spawn that says risen are attacking a keep, and the DE spawns the risen to attack, like in other PvE zones, the DE would spawn when the risen reach a keep after being spawned somewhere else, like DEs happen in WvW.
One potential problem with this could be that it ends up similar to other zones where players push the DE chain to the winning side and it never goes back. To prevent this, if the undead hold no bases because they have been pushed back to spawn, or even if they just hold too few, increase the spawn rate of undead until they push the players back and take over a few bases.
I think it could be a lot of fun for the whole server to work together to fight off the risen menace. If they could get the AI to do well enough to keep it from getting repetitive, and adjust the spawn rates dynamically so it doesn’t end up looking like some WvW match-ups with one side owning everything all the time, I know I could have a lot of fun in there.
