Any attempt to add a flanking model using multiple units attacking from different directions would likely trigger more errors similar to the recent interference bug, wherein having two units in the same province prevented either from capturing the province.Uberlandia wrote:
flanking an enemy fleet should be advantageous.
There is no extra advantage due to 'flanking' in naval warfare. All units have the same vision, range and firepower, no matter how many different directions they are attacked from.
The overly simplified naval engagement mechanic in CoW only allows attacking a single enemy unit and the ships must be dead in the water to attack. Adding a 'flanking' bonus is so far down the list of needed improvements, it should not even register.
