I haven't played Epitaph yet since the update but I've heard they removed every single shield door, which I don't think makes a difference. You can still stand behind the walls and camp with a shotgun, but I also heard they added a sniper to that level (?). Either way, Epitaph is the gayest map ever.

Snowbound without the shield doors is called Boundless. And THAT is fun. They removed every single shield door on the map except for the two front shield doors on the bases, the big back one is gone but the smaller two are still there. No more people going down to bottom middle to camp, it's more about using you BR which I love.
