I've known Reimu for a bit, and this is completely false.
Not sure who you actually are seeing as you are the "masterspy" and this probably isn't your real in game name nor has it probably ever been. If I'm wrong then cool.
The idea that good players don't lose cities is comical and silly. Any good player who plays this game long enough will end up on the losing end of plenty of battles and wars. I have yet to see any alliance, or any player in any alliance, who can successfully win every world and not at least lose some cities during wars. I've been playing this game on and off for 13 years and I have yet to see it happen. Maybe I'll be proven wrong on that one, maybe if you showed your name instead of trolling under a hidden identity that would be another thing.
Anyways. Good luck to you on whatever worlds you are playing under whatever name you play under.
One last thing to add. If you haven't ever been coalition'd and lost cities, your alliance wasn't that scary.
