Before I say this I would like to say I love both WKC and FFXIV.

The problem is we would not see the same kind of online interaction, we would level solo, and people will have been playing a class outside of its intentions so long solo they would not know how to play it with other people.

One WKC example of this is when people use a bow through the story, they use it primeriy as a DD, when they go online they DD, when bow is supposed to be a support class, using their hymns alot to keep tanks healed, to keep mages MP topped up etc, also playing offline you very rarely need to use stances (att up and def down etc) however the online quests require this alot more, and +fortify can be a life saver online if someone didn't need to use it offline it probably will not be set for online play for the harder quests until people start raging.

Another example on WKC is in the quests that only one or two people can transform, when playing offline, there is often no problem with transforming just to dispatch a large mob fast, in quests this mentality will not work, if one person transforms too soon the boss fight can be alot harder, or if someone who has subpar knight gear, they will not be as effective in the fight as someone who has better knight gear.

This sort of thing would happen in FFXIV if they did this as well, because people don't know the mentalities of the community, imagine a BLM that was spamming nukes without thinking, imagine a WAR missing a tanking or DD set, or a PLD that doesn't know how to keep hate.

Its very hard to properly integrate online and offline play, one thing I would have liked for WKC is if they allowed online versions of the main cities (Balandor, Faria, Greed, Albana etc) as a large scale hang out area, and possibly some open areas (Langnish desert, van haven waste etc) to fight alongside other people, rather than just quests infact why not have some quests (free monster hunts for example) in an open area fighting with others, this is the sort of problem with this sort of thing.
