Huh? For me its working fine and you have more ways to flank from south too. You saw the 1 path, where normally no vehicles at all could drive? It is fixed and passable now. From inf you can use 4 flanks into the forrest. that should be enough^^
Northside has 4 too.
But this is kind of offtopic here for Port of Hamburg^^
1. SOUTH TO NORTH FLANKS
2. NORTH TO SOUTH FLANKS
The north has many more flanks possible. The north has two more paths to get behind an MG. Once they are behind the MG, there are two hedgerow sight blockers creating even more flanking options. Not to mention if the units are CQC they will be right on top of the MG before it even sees them. The southern flank path can be guarded my a single MG or mine. The top would require at least three MGs to do a decent job. And I skipped the far right side river flanks. So add one to each
Edit: Notice also that all of the large areas to fight in are North of the tracks. Meaning, if its an even fight, you are in your base. GG.
