I really don't agree with the comments regarding Operation Locker being a poor map, I actually think it's one of the best.
If you don't like vehicle maps and prefer intense infantry fighting then Locker is perfect for that. It only turns into a meatgrinder when the teams are too stupid to make use of all the entry points. I'm pleased that they have included the snow section to allow for flanking, it breaks it up a bit and allows a good squad to break through.
I do however agree with the comments regarding it feeling unfinished. Some of the textures are so bland and boring. It would have been a refreshing change to walk into a building on Golmud Railway for example to find it has an interior. The previous occupants of building in BF4 must be the only people in history to have absolutely no interior decoration or furniture.
Agree with pretty much all that, although the clutter/interior would have to be limited to still allow a good amount of freedom movement wise as it can get quite busy at times around the choke points you mention.
