This is the most important factor of the game keeping the item aspect of the RPG elements going. Currently I partially enjoy just sitting and killing server hoppers, but it would be far more entertaining and a better game if characters were locked to servers. It would help community and it would also make the items and their drop rates properly reflected. I currently have 3 NV and 2GPS, 2 rare guns all just from sitting at NWAF and killing hoppers. I have never even seen any of the stuff I have in the world, but I have an ample supply delivered to me by hoppers. That said I would prefer if characters were locked to the server they were created on.
