I have 2 suggestions.
Firstly, the WvWvW… for PvE.
Making a PvE map that work like WvWvW but instead of being PvP, making it against monsters (Dragon’s minions) would be awesome.
You know, just like in Lord of the ring where they defend that keep.
The possibilities are already there… Risen catapults = trebuchets, giants = siege golems, using risen bulls or something could be the rams… etc.
Using events to send ennemies troop from their bases to keeps or towers.
Or maybe design just one giant super keep that we need to defend.
Wouldn’t that be great? (Personnally I’d love to use a ballista on risens. :p)
For the rewards, make them as low or lower then WvWvW and give the same kind of passive bonus from controlling keeps and towers (giving other passive like magic find, damage increase or condition duration, etc.)
Because right now, other the dungeons, all I see for PvE is farming mats or events… there is no actual fun dynamic stuff going on in the PvE world.
I want to feel like it’s actually a war out there against zaithan.
My second suggestion would be… well… guild wars. Being able to go at war with another guild allowing us to attack members of the opposing guild in the PvE world (at the exception of cities). Make it cost money to go at war and only if the opposing guild accept guild wars.
