As of now, there is absolutely no limit to the amount of structures you can create. To combat this, you guys added siege weapons, explosives, a purge, avatars and so on. So far, it’s fixed nothing. Some of those features cause people to quit the game and still there are players who will create massive bases of no life proportions that directly impact the entire server and it’s players. Maybe you should cut the root before the issue even is able to grow and that can be done very easily. Simply, make it so there is a limit of how many structures a single player can put in the world at a given time. It can be a high number and maybe it can increase as you level, but we NEED a limit.
Building should be strategic. You should put together a base that does it’s intended purpose, rather than grief players, block resources, and take large portions of land that you don’t even need. Remember, we share servers with other players. Unless you’re a high level, it’s impossible to eliminate everyone to have enough room.
