...seems the horrible systems Blizzard call Cross Realm Dungeons and Cross Realm Zones, which a large number of people playing WOW detest with a passion, is coming to FFXIV:

Since it may be difficult for newer players to find others with the same objective, who are of the same level, the system will bring people together from multiple worlds. That way, you can play what you want, when you want.
This is a recipe for disaster, the long experience of the cross-realm Looking For Dungeon has amply shown it breeds excessive greed and ass-hattery, because players can be jerks and then return to their own realm with no repercussions with regard to their community reputations.

Cross Realm Zones has destroyed large parts of the gathering game, now the over-competition for resource nodes makes leveling gathering a nightmare.

Please Yoshi, I beg of you, DON'T inflict this community-killer on us.
