What does it do? In 5e it adds the dex modifier to the offhand attack damage, but in this game, it's already there. The fighting style claims to add it, but as I said, it's already there. I could prove it with tooltips and roll logs. The attack roll, to hit, though, only gets the proficiency bonus, so logically it could add that to the roll, but it doesn't. As it stands right now, the fighting style has no advantage whatsoever, as all the bonuses are already there.
