This age has been very tough for us to get wars. Mainly due to our setup and nwpa would have to be my guess. Most of our wars find us warring up, and into more troop count/peasant counts. Warring up is usually your best bet to get wars quickly, but usually the tougher longer wars. In recent ages i think 7-8 wars was more common due to the ease of access NM had. NMing and chaining can make a lot of wars min time, thus leading to more wars in a given age.
