I'm going to reference a game that is not FFXIV. Though it's something I would like to see because it's really awesome, and as far as I know, no other game has done it, correct me if I'm wrong(except one).
Dragons Dogma
I think it would be amazing if they stole their idea for an nm. I don't really care if it would be instance or open world, open world would be awesome though.
Basically I want them to add an nm where it takes people from every server to beat it, collectively. Whomever participates in the fight gets rewards accordingly when it dies of course. Now, what about spawn time or what have ya. Well, I think my NM idea would be an awesome thing to throw in here. If they are keeping the anima system:
"Because anima is a life energy deal(stealing this from an anime) it could make sense that it creates an entity of some sort. Kinda like in Index(have to watch it to know what I mean). So, when x amount of anima has been used through out all of the servers, it will spawn this entity.
Why do I say all the servers? Well, this is a way they could make use of their, dungeon finder deal they are going to do(I don't like by the way). So, what will happen is when it spawns(it can even wonder the world as a ghostly figure that you can't attack, until its a whole body) it will select 20 people from each server whom last teleported(that are level 50) and spawn them in an instance with this entity. Now, it wouldn't have any special drop, it would just be a fun random activity that we the people caused. (something along those lines please discuss this!)"
Now, instead of growing stronger each time it dies, it will go stronger by how much anima is used when it spawns. Now, this could end up being a few day fight, which can lead to legal issues down the road. So it would probably work best as an instance fight that can be done in 30min intervals(just like dragons dogma) with a party that's more than 8 people.
