Yes, I know that this sounds maybe little stupid to you, but I have to ask. What would be the best solution, if I had a long border with an AI and my army is grouped in one province(which is quite obvious to me) and then AI´s army decides to start overrun my lands. My army is other side of border and so, if i wanted to catch AI´s, it would take a couple of turns. If I go and catch the army, AI will "dodge" my army and continue rampaging. Should I attack straight to AI´s capitol or hunt AI´s army down? I know, that I will catch his army sooner or later, but other AIs are getting stronger during that. Maybe buying defense is a solution, but its is too costy for me.
