played endless hours of KF1, so have you, we all know about welding doors and camping. It's fun.
Can't do that in KF2. At all. In fact welding doors is a nuisance! So annoying when that brigade of supports starts welding everything because as we all know, those doors aren't worth any XP open.
When that unspoken "its time to bug out" time happens, the group scatters, survives, and regroups.
Hard to 'scatter' through a welded door.
Not even talking about the "sooner or later doors explode" thing, which just says "even if you DO find a good spot to camp, surprise! it's not".
The only use I have for welding now is escaping a rampaging scrake or fleshpound I'm not ready to deal with yet. Run through a door then quickly weld it behind you, takes some practice but very effective.
I'm sure the modders will be out in droves creating "long hallway of spawn doom into a gun shop" maps, but as things stand now, at least could Tripwire please remove the XP for welding? It encourages really annoying trollish behavior.
