"Off-hand weapons will now equip into a character's main hand, if no main hand weapon is equipped."
This sounds like it is going to be quite the annoying change since I often use offhand-only weapon sets when I'm using scrolls.
Rather than "Potency in offhand" weapon-set-> Heal scrolls in main hand. Potency item gets moved to main hand, use scroll and potency item becomes unequipped.
Same with Masters touch scrolls if you are TWF. Can't have them in offhand slots to switch to each easily, will have to mess around in the inventory screen every time.
