Acually i think that the only way to deal with proxies and dual loggin is:
1. Make the game registration for one account with few characters (however this works only with pay to play games, and even there some people could pay for more accounts, but that wouldint be all that bad thing no? However as we know this game will not become pay-to-play as far i am concerned)
2. Make one character enough to work well for everything he needs. Scouting, Mercs world map, tent making, new member base adding and bringing. All those things need two players to do at least. You cant attack a town without scouting it (ofcourse, right now one person scouts and second is ready to fight, but scouting is boring, really), the whole thing with mercs on world map camping grid spawns is somehow tactical but if you think about it its just ridicules (in my opinion everything spawning on your head or you spawning on others head like in some encounters is ridicules acually). Tents, as you cant have a crafter and a good fighter in same character, you have to have two characters, and its good for both to see the tent, you either got a friend to log into one of those or you risk your character to be stolen, or you dual log... Same with base (hopefully those two will change "soon" as it seems).
