Royal buildings Discussion

My thoughts on Royal Buildings.
1. The Royal Training Ground is good because it produces 1 extra militia and can be brought to lv 3 fairly easy.
2. Royal Barracks are good because they use less purple hammers to make Paladins.
3. I don't think Royal Mines are worth the investment when there are so many other buildings that are.
4. Royal secondary buildings are good after the military ones are built. They produce more product and are not too expensive for upgrades verses the regular ones.
