BTW! "National borders" and distance limitation beteween towers/CC/fortresses are also ugly. At AoE2 AI-player expand only on his area, and build only lumbermills and mines at distant lands. At 0 A.D. AI trying to grab all map (not bad) and you can't put Store to steal resources right under it's nose because of dumb "national borders" (very bad!). The most annoying thing is that AI's national borders may "convert" your towers, which were on your national border. Could devs at least add something like "Ox Cart" just like it was at Age of Mythology? I don't see any reason why I can't steal unprotected resources on enemy's lands. And you shoud do something with siege weapons. Just 5 rams can win the map because destroying CC authomatically starts decay and AI run to towers and fortress to stop it instead attack rams. National borders - most evil game-ruin thing what may happen at RTS.
