Fix current issues before adding new content that creates MORE bugs...?

The game, in its last two updates, has added content and fixed bugs without addressing the fact that the zombies teleport and glitch through walls, which has been happening way longer than you should be proud of.
How about fixing THAT since the zombies are the MAIN LURE for most people in the survival genre?
I've died too many times to those, amongst other issues, than by legitimate encounters with zombies, humans or animals combined, as have countless other players. It's unplayable in this condition since dying through no fault of my own is just frustrating and unenjoyable at best, and I know I'm not alone.
It's an AMAZING game when working appropriately, but I'm done beta testing a game in its condition. So, before adding any other components, if ever for all I care, can you PLEASE fix the zombies???
I don't play many other games when DayZ is running properly because it's fun, interesting and different from any other games similar to it... but these zombie issues are maddening and frustrating, and you should want the game to be fun and enjoyable... Right?
