Zed deviations suggestion

Something that made the original Killing Floor slightly less immersive was the fact that zeds of the same type looked exactly similar. A feature that might be interesting (at least in my opinion) would be the implementation of small changes/defects/looks amongst zeds of the same type. For instance, instead of all gorefasts having the exact same model, it may be possible for them to have different blades, eyes, facial structure/attributes, tongue sizes, etc etc. There could be several attributes that could be randomly selected upon spawning, so that the zeds have a more unique look to them. That way, hordes of zeds may look that much more dynamic and horrifying. However, I understand that this would probably be an inefficient use of resources that many people may not even appreciate. But hey, it's something possibly worth considering down the line in future releases. Any thoughts, comments or further suggestions are more than welcome! :D
