There are bound to be more than 30 soulstones for Dragoons. The role of Dragoons in Ishgard is brutal with likely a pretty rough mortality rate over the 1000 years of war. So what happend to those soulstones of past Dragoons that were killed in action? It would be impossible to gather all of the fallen soulstones. You have these fighters who jump great heights to battle dragons in the air. You have a city that is perched over a vast chasm where fights up against the city walls didn't seem that uncommon. There is tons of room for past stones to be lost so there has to be a way to recreate them.
Not only that you have the training of new Dragoons. First you start as a lancer of course and work your way up but what happens when you are first given a soulstone? It becomes training back from start to learn the Dragoon ways. I fail to believe that any of the Dragoons didn't have a rough time learning how to jump and harness that power to a precise point. Yes you have that past knowledge and perhaps know how but it's not going to be like turning on a light switch.
It's going to take any new Dragoon a bit to adjust to the soulstone and different fighting style before they are worthy of being titled as Dragoons and put into service.
