I agree with what they did to a extent.
In BFME1 i loved the fact that humans and that had a wall, it was the coolest feature.
In BFME2 they destroyed the fun of walls by not making the walking on able.. and i pretty much decided screw walls they're useless.
In DoF there's walls they're pre-set but it doesnt seem as bad.
I would LOVE TO LOVE TO LOVE, be able to place my gate location, and the towers like the above person said.
But i agree to the whole ******s placing walls everywhere thing, does ruin it and the realism involved.
