Job change cooldown, why is there?

[Naunet]

Too much abuse potential, especially when the cooldown can be worked around by being in town when you switch. Which will *not* trigger the cooldown.

I wonder if that same cooldown immunity could be extended to rest areas like camps, too.

Please, tell me where the "abuse potential" is. You can't change classes in combat and you can't change classes while in a dungeon, so there would be no incidence of swapping classes mid-fight or in the middle of an instance. There's not even any chance for PvP abuse, since XIV does not have open PvP servers, and I'd be willing to bet the arenas will follow the same rules as dungeons do with regards to disallowing class changes. All the extra CD does is create a serious annoyance for those leveling multiple classes out in the open world.
