Welcome to the dark side. Everyone reaches the point where they simply accept the fact that the Main Arena is a free for all. Anything goes, anything can and will happen, and when you first stop caring how anyone else plays or what anyone else does, you can finally log in and fully enjoy the game for what it is.
Structure? Special events. FSO, Scenarios, Snapshots, KOTH any number of regularly scheduled events each having a different level of immersion and restrictions.
You are on your own in the Mains, no one will ever play how you want them to play or expect them to play. To have an imaginary expectation of what people will say or do will never turn out well and will always disappoint you. If a group gets together to defend the kingdom from the horde, Great!! If not, no lost sleep here, simply don't care. The map will reset and all that territory lost will be recovered. I shoot someone and they don't like the way I shot them, who cares, I was shooting them not inviting them over for thanksgiving dinner. If I was concerned about what they might say or think about me, I wouldn't have my fragile little ego up in the virtual sky playing with guns. Game has 2 levels, pleasant or irrelevant. The negative wasted BS just isn't worth the little time I get to actually play so it doesn't get my attention.
I hate surprises. If I expect someone to face shoot me, or ram me, or bomb my GV, or pork my base, or any number of things that will spoil my flight I will work tirelessly to avoid those situations. Then, when it doesn't happen, I'll be surprised and pleased, and never disappointed in someone's actions again.
