Alright let me start off by saying I'm no pro at this game. I enjoy it yes and am a huge history nerd so when I play I always envision a history for them. For the random spawns I think of them as revolts or uprisings, which brings me to my points. 1) These events can actually be quite annoying and there should be the OPTION to disable them. This all comes back to player choice, if you want to face a difficulty and have a history like I do then by all means have spawns enabled but for those who don't then let them play as they wish, it doesn't affect you in anyway. 2) Make these events make sense, given my previous statement on how I saw these a revolts/uprisings perhaps these spawns could be changed to have the mobs be the same race as your empire and still make them global by saying like a wave a revolts spreads across the world as a result of X 3) These spawns with are not tied to revolts could and should appear outside of your domain and could be scene as demonic invasions, which are programmed to seek out the nears Mage city and lay waste to it. Doesn't really change the gameplay, just adds an ingame reason for it. 4) I do like these spawns as they reinforce the need for a "home defense force" and can be kinda cool if properly handled, that said I have to go back to my point on player choice and say that this should be an option, if someone wants to have a horde to march across the world with it should be their choice to play like that and disable these spawns.
