I was unaware that there were doors that could only be opened by defenders, else I'd have used them. I tested a bunch, and they were all team-neutral. I'll test the particular doors you mentioned.
The one-way doors opened by either team do allow for the attackers to open the doors for their allies after they've gotten in though, which is neat mechanic.
EDIT: Well hot damn, that's neat, they do. The door in the gatehouse has been replaced. The door to the flag area I'll leave the way it is until some real matches can be played. The OP has been updated with the revised files/screenshots.
EDIT EDIT: Finally figured out that not having all 62 entry points placed makes the game just spawn you wherever the hell it wants, placed entry points be damned. After extensive respawning I haven't had any trouble yet.
