Why don't all classes have access to an offhand? Maybe i missed somewhere where devs addressed this as to why they decided not to add offhand, but is it that difficult to implement and find a balance? Omitting the DoH and DoL. The only classes with an offhand is a CNJ/WHM/THM/BLM/GLA/PLD all of which are shields of course. But it would be nice to see an off-hand implemented in the future for all classes.
ARC-SCH-SMN should have a Pen off-hand. (There is already a pen in hand when they cast spells why not make it an actual stat giving item).
ARCH-BARD should have a Quiver of Arrows, but as a single static item and not one that uses consumable ammo.
WAR should have a Chain that wraps around its non-dominant hand.
PLG-MNK offhand should split stats for a single glove to be share with just another Glove.
LNC-DRG should have ..ehh? Maybe an Arm Dampener for them heavy thrusts.
Get what im saying? Having an offhand that makes sense. Now i wouldn't want SE to adjust existing items already, rather add the ability to use off hand items for future weapons added into the game.
