I've been thinking about this and I think 15 seconds would be perfect.

Combat logging also renders the whole idea behind items like handcuffs and harvesting blood from live "prisoners" useless.

Maybe they could add a logout timer. So it would take 15 to 30 seconds to log out and if not done legitimately (either by a pulled modem plug or alt+f4) then it keeps you in for 15 seconds.

I think you misunderstood me. I'm not angry.

As for your points, this issue was respective to combat logging and not server hopping. Please stay focused on the topic and its issue.

Combat logging has never been much of an issue in previous games that have a loot mechanic when addressed with a "ghosting" method. Every MMO in history, for example, has quickly resolved the problem by allowing ghosting. It's not 100% perfect, but its pretty much the best system. You state that you cannot find a safe area, but how is it that I can easily find a safe spot in which to log at? I have had zero problem logging out safely and logging back in wit my character intact. If you are having problems perhaps you should look at your own contribution to the issue?

There are no better solutions because the best one has already been
employed. If someone randomly disconnects then they stay logged into
the system and this has addressed the issue of combat logging. I can
agree that for the paranoid types an in game logging system may be
beneficial -- perhaps a lootable sleeping bag that takes 20 seconds to
deploy which logs you out at the end of the countdown would be
sufficient. Keep it simple.

This happened to me and 4 of my friends AT EXACTLY THE SAME TIME. 2 of my friends avoided it. Here is what happened to us and what happened where it was avoided:

Character loss: 6 of us were all playing together, running down a road. The server was scheduled to restart. We played until the restart and were booted from the server. We waited about 20 seconds and refreshed and then joined the server once it came up. It seemed to just hang there saying "Please wait" for me and 4 others who joined off me. We were all wiped.

Avoided loss: 2 of my friends logged into another different server at exactly the same time we did. Quite simply, they were spared. The issue seems that it may either involve or become exacerbated by logging into a server that just booted up.
