Good evening. Two-weapon fighting has been bugged since release. Initially, the str/dex modifier was not added to off-hand attack roll calculations, but the modifier was added to the damage roll, even if the character did not have the two-weapon fighting style. After patch 4, the application of the modifier to the damage roll only to characters with the two-weapon fighting style has been corrected. However, the modifier is still not applied to the off-hand attack roll.
