Sorry if this is the wrong place to post this, but I figured this is an issue with the game.
Combat Logging and Server Jumping where people stock up on mass amounts of gear from multiple empty servers, and use multiple servers to get the jump on people they are fighting with, is a major issue with the game currently, One idea I feel would work very well is to make it a One Character per server rule.
Basically your Character is locked to the server you made it on, there for it can Not be taken to another server.
It will stop people from combat logging, moving around on another server then logging in behind you or in a better position to you and killing you unfairly.
Also it will combat the whole jumping between servers to stock up on ammo, weapons etc which, Trivializes the survival aspect of the game.
I don't see this being a problem to implement considering this is supposed to use MMO like architecture, and all MMO's already have this in place as standard practise.
I feel this will also encourage people to stick to one or two servers, which in turn will create communities, rival groups, gangs and great encounters.
