Of course it is L2P, you should know that retreat paths have stupid logic behind it.
Did you any reason to go behind enemy lines?
Did you you recon the safest retreat path?
Did you actually think the British opponent would more likely use the Bofors over the AEC.
Since this is not about a replay I uploaded or a game experience I described stop asking what I did or did not...
Flanking moves are supposed to be rewarded not penalized.
The AA emplacements have enough utility without the blocking or retreat paths at a significant area.
Choosing retreat path in certain map is not really an option.
And I still have not seen a singe argument why Bofors should be good at killing retreating infantries...
This can be easily fixed Reducing damage to units on retreat without having any other impact on the A.A.E.
