Blocked Storms, they attack in melee and deal half damage, but according to the description, they should deal full damage. Is this a bug?
The description should match reality, i.e., yes, this is essentially a bug and needs to be fixed (either the damage or the description).
The situation is similar with the ballista - either don't state that the number of shots is limited, or limit them. Ideally, the game should be complete and consistent, in my opinion.
