The next FFXI update, coming this month, will be making adjustments to the Battle System in the game.
Two major changes are revisions to the use of two-handed weapons, as well as modifications to several jobs.
Up until now, there have been instances in which the attack frequency and speed generated by dual wielding would greatly surpass those of two-handed weapons. We have since examined this issue from every conceivable angle, and as a result have decided to reconsider the frequency and delay calculation methods for two-handed weapons.
This month's version update will see the introduction of a new type of gear called "grips," which players can equip in their offhand weapon slot when using a two-handed weapon. We are also planning to apply changes to associated weapon skills as well.
