There are, perhaps, better places to get a more focused set of feedback from people who actually understand the nuances of Killing Floor; however, I wanted to get some talk about it going someplace very open... even trolls present valid views from time to time.
My feeling is simply this: I concede the map is very challenging. It's overall design philosophy is to push the player(s) around. There are many designed hold out locations but the lesser of them are also designed to force the player(s) to either be exceedingly/outstandingly good or get flushed out. That said, I also want the map to be playable and enjoyable not abusive.
Actually that won't work on HOE. It's either stay on a place and survive or get overrun and die. I do understand the nuances of Killing Floor, have all HOE Achievements but Hospital Horrors and was playing the mod since 2005, however running arround in a map in order to survive only works till suicidal.
Actually it's fun changing the location during waves however on HOE this will most likely end fataly.
But i wouldn't change anything on Bedlam, as it's fun to play imo.
To improve the gameplay of KF it would need something that will force you to change your location. Otherwise players will always try to survive and that works on a good place.
Bedlam also has an ideal place to camp and that's the "balcony". I totaly see your concerns, however Bedlam is a very cool map and adds a lot of action to Killing Floor, if you'r playing on hard or Suicidal.
It will allow you fight through Hallways and find places to "rest".
BUT:
On HOE some Crawlers kill you in seconds and that's why a room with Crawler spawns in it just will make you mad and get you killed once you don't pay attention or have to kill a FP and so on. This then will get frustrating and you'll search a good place, which you then will always use on HOE.
In a nutshell: The slightes mistake and your whole squad is gone! On HOE "get flushed out", means getting killed most of the time. And that will then just make it frustrating if you need the best players to stand the slightest chance on the wrong place.
On HOE servers I only see players camp on one spot, however that's always the same in KF.
To conclude:
You can make the map easier and thus make it less attractive for games till Suicidal or make it easier and less frustrating on HOE.
I won't change anything on it, as it just is fun to play in my opinion.
The map has an awesome atmosphere but sadly some places never really get used.
