@BloodyWiesel very true. One of the things I liked about the DayZ mod was you could actually choose whether to engage the zombies or avoid them. Giving you the opportunity to think twice as you say. In the standalone, you have no choice. If there's a zombie in the area, you will have engagement whether you want to or not. Even if they don't fix the immediate attack bleed or wall clipping, it would be nice if they eased up on the survivor detection.
@avkronnie as much as I would love to have an axe, I haven't been able to find one. Maybe loot drop increases or item respawn rate should be addressed as well. I didn't even notice their ability to hit you through the floor/ceiling, though I have been able to close a door downstairs through the floor while being upstairs.
