Unbalanced combat. Anyone with more power or better armor is going to dominate you. The team combat isn't fun and requires 100+ hours to do anything. Not enough space if there's 100+ people in a faction. There needs to be limits to how many people are allowed on a server. It just doesn't work. The whole game is a train wreck and unplayable with too many people. There's not enough land and people steal spots next to your base that you need to mock from in order to even build forts to leave area.
