Monster Park Dragon Canyon

This. It's exactly the same except:

1) Easier to find people.
2) More areas (leafre, ToT)
3) Rewards

Therefore better. Also it's easier to incorporate new areas into this rather than invalidating every other place that comes out. The argument that it's useless to go anywhere is false because future ereve mobs still drop dream fragments to forge stuff with.

I really would prefer it if they were to just make the entire game party play, rather than make a party play area that incorperates snippets of the entire game.
