new classes and off hands?

[RiceisNice]

On DoM and DoW classes off-hand slot is for shield. So the first way is to think about how the new jobs can hold a shield while fighting with the main weapon

It doesn't have to be a shield. It can be something you hold in your secondary hand, or a compliment to your weapon, like the aforementioned quivers, or enchanted objects. Of course for the latter, it means that the job animations need to be designed with it in mind (since a lot of the casting animations are done with both hands holding the staff)
