All in all i liked the changes made for Age 68, with the exception of certain effects related to the massive boost to NWPA that were probably just not properly considered when designed and implemented.

1. Dragon costs need to go down and health needs to go up. With such a huge increase in province/kingdom net worth the cost of dragons increased substantially, and with the high troop values they also die way too easily, it's been a very disappointing age for dragons.
2. NW based gains made sense before, but not any more, not if age 68 changes are here to stay. A well played and "pumped to perfection" province shouldn't be the prime target for someone substantially larger than you who's nwpa is low either due to just being fat or due to deliberate net worth abuse/manipulation to allow for effective bottomfeeding. For example leaving acres unbuilt and/or using huge stacks of soldiers as a NW gain/loss mechanic to optimize your gains (biggest stack i've seen was over 55k soldiers)
3. Give back 72 hour forts, with everyone and their mother tracking stance change server wide, entering fort stance is basically an open invitation to attack and you end up spending the 24 hours under actual full protection, recovering from entering in the first place.
