SO first of all thankyou for the proper constructive feedback. The rotten trees are dealt with as they are all on nocollision now... i realised that its a problem before. Rocks will stay the same for now.
There are 5 exits of the tunnelsystem and yes two of them are in the objective itself but there are a few around it( and i will add another two exits in a future version).
C objective is usually fine(i mean i played the map a lot of times and there were multiple times the defenders hold the attackers back on C. Also the big problem atm is that the defenders dont fall back when A and B are taken. But that is a problem of the game itself... I am working on a mod though to make a proper moveupzone
The pathing is directly taken from bf:vietnam so is most of the important Objectives (like the Temple and Shrine).
And last point the line of sight: It is intended that you only see a very limited distance. It maybe not as fun for some people but i really wanted to pass over the feeling in that the vietnam war had: deep untouched jungles. And keep in mind that they didnt dropped Agent Orange or Napalm on every part of the jungle... Lots of fights took part in jungles with bad line of sight.
And If you get to Foxtrot you get an more open Objective though.
