Last week developers announced that the guildleve system in Final Fantasy XIV would be overhauled. A new developer blog has shown up on the Final Fantasy XIV Lodestone that lays out the details of exactly what that 'reform' means.
Regional Levequests
The skill point bonus will be abolished for battlecraft leves. The amount of skill points awarded for slaying individual enemies will be reduced, but this will be offset by the inclusion of skill points as a reward for leve completion. To accommodate this change, factors such as recommended/actual rank disparity, completion time, and partial participation will be made to influence the amount of points yielded. In addition, leve linking and sharing bonuses will be reduced, while the maximum number of linkable leves will be raised.
