It is not arbitrary at all.
Any flanking maneuver you do that puts you in the position where you have to retreat through an enemy strong point is a bad flanking maneuver. Not knowing the path your units will take on retreat is no excuse. Retreat paths are not random; it's simply something you need to learn and it separates the people who do good flanks from the people who do bad flanks.
As I explained it is not what I know or don't know. Retreating paths are map related and there maps that bofors can shut them down. Its not about know or planning its about if there is an option...The current performance of bofors limits counter play without actually adding anything to the game...
The Bofors does not have a lot of utility as it is. It can not move; this is a pretty big deal.
Let me see now it can kill soft targets, suppress infantries/ rakketns, barrage support weapons, shut down light vehicles, engage airplanes, protect infantries and wiped out retreating infantries.
Yep it has little utility...I guess the 2cm flak emplacement has more
If wiping out retreating squad is something that AA emplacements should be able to do the 2cm flak emplacement should be able to do it also...
