I am in the "fine if IC" camp. Having been on both sides of it, I just can't say I worried all that much about the "drone sitting in realm and relaying orders" spying, and the actual dedicated spies often had excellent stories. I mean, seriously, the best story in the whole Arcachon-Sartania conflict had to be one deep-cover spy that eventually succeeded in turning Arcaea and Arcachon against each other.
