I agree with much of what has been said - for me the Zeds should be very aggressive and dangerous, otherwise where is the Zombie Apocalypse? Having said that, Zeds walking through walls and closed doors, hitting you through floors and ceilings, and respawning in your face, is the overriding ridiculous situation (imho) that is keeping many servers empty (or very low pop). DayZ has been a triumph so far, but the Zed thing is vastly reducing my enjoyment and I am far less keen to play now. I realise that it is encouraging greater group play to survive and that is a great addition to the game, but some folks (including me) like to lone-wolf it sometimes, just for a change and that has just about become impossible with Zeds 300 metre sight and hearing at present. I suggest:1) bad eyesight, but good hearing for the Zeds. 2) being able to sneak past in crouch 20-50 metres away. 3) being able to sneak past in prone 10-20 metres away. 4) Zeds not running through walls. 5) Zeds respawning after 30 seconds and at the location where they died. 6) I like the earlier suggestion of different types of Zeds, some fat and slow, some old and easier to kill, and how about some children Zeds to add a possible moral issue to the game? Finally to those who say STFU, it's still an Alpha - I say Rocket and the team have asked for constructive feedback, so here is my tuppence worth. See you at the Airfield (any one of them).
