I am just wondering what everyone is looking for in PvE in the World. Something different, something new, or just some familualar. Granted this poll is just for the world no real group play like instances. So keep that in mind before you answer. I have played a few MMOs in my day, I myself would like to see something new than just the same old generic spawns. It is nice to know where the spawns are yes, but I would love to see the world change from day to day/week to week, and so forth.
Random spawns are quite fun, like finding a stronger version of whatever mobs are around that has better loot and is harder to kill or random spawning boss-mobs, it just adds a little variety to seeing the mobs you know will be there.
But invasions are really fun (thinking of UO type invasions), I enjoy seeing “main city is under attack” or whatever and then going and getting 1 fps and killing everything I can see
Warhammer, and i mean the original Warhammer not the tragidy mythic did had a great concept for mob spawns. Mobs spawned at random points in various areas, as they patted around they would group up, these groups would then travel a different route across a zone, like a hunting path or migratory route. If enough of these joined up and they were say goblins or orcs then that group actually made a little mob camp, if even more moved towards the camp then the camp sent out an attack on the nearby cities, like mini live events.
It was a fantastic idea, it meant if players did not do the quests or what not to keep down the goblin/orc problem then it actually turned into a problem. This also meant that x,y bots couldn't easily predict exactly where mobs spawned as there were a heck of a lot more options.
