Hi Rocket, I'm also bit worried about the Alt-F4 thing and agree with much of what -Cdn-Chard is saying above, basically how do you distinguish people server hopping for loot gathering/death evading purposes versus people server hopping trying to find one that doesn't have cripplingly dangerous lag? Particularly over the weekend there I spent about an hour with my friend trying to find a server which didn't have us and every zombie running on the spot for ages every couple of minutes. Think you need to stabilise the gameplay experience across the servers before you start punishing people for switching between them. It's really difficult to spot a "genuine" alt-F4 by just looking at logins/disconnects. You might need to consider "did the player take damage shortly before leaving" (Although I've alt-F4'd before to avoid dying at the hands of an invincible zombie that broke my legs, had me bleeding out and just wouldn't die no matter how many times me or my friends shot it - lag related zombie issues can be horrific) or "did the player get shot at but not hit shortly before leaving" (also difficult to determine - could have been his friends shooting nearby zombies). Like someone else said - this is a horrible, horrible problem to try and solve, and I appreciate you trying, just voicing some concerns. I also appreciate you need the data to do the analysis to experiment with solutions, so by all means collect the data, see what you can do with it etc. but I'm not sure the time has come you can start with the actual punishment. One other note is the zombie respawn rate seems ridiculously high at the moment - I quite like the new behaviour and am glad the deafness is being resolved but I kind of feel that once you have cleared an area it shouldn't immediately within seconds be repopulated - we've started having to do stupid things like identify a zombie to try and not kill, which is spoiling the immersion a bit - don't kill that last zombie or you'll immediately have to deal with them all over again and end up with a constant non-stop swarm repeatedly coming after you - feels too much like gaming the system and breaks the feeling of the persistent world really badly. Overall though, thanks for DayZ and keep up the good work - the most interesting gaming experience I've had in years!
