Is BF2 engine able to change Anty baserape line while flag is capped.
sadly not.
this is a great idea and I have wanted this in FH since years back, even in FH1 maps. But no, we can't do it as in BC2 where the combat area is re-drawn after certain flags/objectives are taken.
we could fake it, by spawning a huge kill-object at each flag, that kills only german players.. but this feels like a haxx, and I dont know how we would communicate this to players.. perhaps by drawing push-similar huge red circles around the kill objects on the minimap, but tbh.... this is not intended to do in this engine, and the only thing we would end up with is a messy, buggy and un-clear feature that would annoy more people than it would please.
I love the idea though, it would allow us to move away from the old "conquest" maps and create "mission" styled maps never seen before in battlefield.
