I had quit playing the game for several months because I greatly dislike the coalition system. i think it's a good idea, but it's not executed well at all. Here is what just happened to me and I think it's total bull. I was playing as Austria. I did not have ANY Aggressive Expansion at all with ANY country. I then declare war on Venice with an Imperial Ban Casus Belli. I then take over 3 provinces (all of which gained claims due to casus belli). Let me repeat that.... I took ONLY 3 out of thousands of provinces in the game. I then got a huge coalition against me of about 20 countries, including France, Sweden, and many others. I still won the war, but it's extremely frustrating that I declare war once in several decades and end up with a huge coalition against me. To make matters worse, coalitions don't dissolve in war time, so even though I peaced with France, I then was at war against Muscowy protecting my allies. when I was about to peace with them, the truce was up and France declared war on me again.
So, in other words, what the f**k.
