I understand how certain parts of this work. I know you get bonus and you build points by having rivals or declaring war or taking provinces. I know you can only pick or change rivals while your at peace. Playing as the Ottomans I can pick certain rivals. Who I can pick is increasing in nations since the beginning of the game. The frustrating part is loosing a rival and then only being left with 2 or even worse then you are hamstrung a bit. It seems strange that I can't pick the Timards(is this because of the type of government they have tribal something) who are huge but can pick smaller countries. I still have Venice as a rival but they are down to just provinces around Venice right now and I don't know how much longer they will last as a rival. I've searched online for more info on them and it doesn't to be there. The basic question is how can you tell if a rival is no longer going to be a rival anymore.
