as regards to exploitability, i am not sure about it. if travelling troop slow takeover down, you can use delay arrival once and that would be about it.
If you are only able to delay one turn, you are doing something wrong. I've done it for days at a time with my army to great effect.
i would use subject of the thread to pose one more question - is it a bug if the realm whom we hate can begin friendly takeover against us (seen on dwilight)?!
Similarly, Port Nebel has just revolted to Corsanctum again. However, last I checked, they hated that realm more than anything in the world. Well, them and a few others.
