Yeah I do agree with this idea. Since this game s still on alpha stage and Rocket himself admit this game needs more experiment before going to the next stage, why don't they constantly change some settings and see how the community respond to it. Before that, all we do is to post subjective judgements here.
I personally take it as a survival game, not some horror game that suppose to scare the sh*t out of you...so I like the current settings, the zombies are feared because of their role, not their lookings...
If it really happened to all of us, it's like "you either die as a hero, or live long enough to see yourself become a villain". Quote from Batman, Dark Knight
