Abyssal Bow / Heartpiercer still do not calculate the abyssal arrow when calculating the final damage, this might not seem like a relevant issue to age of war but corrupted builds have little options left for weapons to use with the new stamina system. The arrow is responsible for over 50% of the weapons armor pen and around 30% of the potential damage. Bug reports have been filed, and while a fix is not as important right now as the camel mounts or demolishers it would be nice for it to be acknowledged.
