I'm not absolutely looking for an house rule. In this situation, as you said, there is a lot of parameters. But during our last game , we have encounter 3 issues with the maximum of visibility when Units are in a wood, or a BUA.
Charge with oblique angle are common.
Unit in BUA too.
retreat and pursuit also.
The next turn, my opponent needs no MO to save his unit. For me ,i need at least 2 MO (2 turns ) to charge again. It's very difficult to attack in Blucher, ( Defending is easier) so if i can find something that could help players.
After severals games ( not more than you of course). I think that unfortunately , we must create an house rule for visibility outside a bua or a wood.
probably unit into a wood or BUA , can see outside if there is less than 1BW between the unit and the border of the wood or BUA. ? Or Unit in a wood or BUA have 2BW of visibility if there is less than 1BW between the unit and the border of the wood or BUA ( that prevent to be shot at short range by artillery without the possibilty of charging her or to be able to charge first a unit in range)
What other players think about that ?
Thanks Sam for your attention to this topic.
