I feel like camping sometimes doesn't get enough credit: I get to blast hordes to pieces while coordinating with my teammates, focusing on specific targets, communicating when help is needed and depending on others for certain tasks.
I find it quite heartwarming when the game allows me to form a nice firing squad that is dealing with different threats with brutal efficiency (and, if you screw up, you're done, period).
That is not to say, however, that camping should be the only option nor that it should be easy. I agree that 1 way safe campspots make things too dull and the game should enforce at the very least some dynamicity to the fight. On the other hand, kiting shouldn't be the safest way either where you can just run away and have the zeds form a nice row for you to easily pick them off and stay safe (and take like 1 hour per wave...).
I've done my fair share of both kiting and camping in KF2 and I feel the game is already doing fairly well. I do agree with the sentiment that doors having a hidden health pool is perhaps a bit unfair (although part of me likes the idea - it makes sense realistically although gameplaywise it makes welding a LOT less useful) and that teleporting zeds are stupid.
I've played a few games where I camped with my team in one area and then slowly backed off to another place when the situation started going down, which is something I quite like.
With all that said, I really wish KF2 had more voice options. The automatic callouts and battle chatter are nice, but I miss having my 10+ keys bound to different voice commands...
