Classes.

When dragons have similar abilities and behaviors, they may be assigned to the same class as each other. Dragons in the same class are more likely to be related, but its not garenteed. This is because of convergent evolution. Not only that, a dragon may also have close reletives that belong to different classes. A dragon only needs too meet some of the criteria too be put in a class.

Some dragons do not fit the classes they where assigned too so I'll be changing them too classes they fit with better. Also some dragons have multiple classes. So I will also give dragons multiple classes if I think they fit. Wich ever class I think they would fit in with better will be listed first.

Dragons have stats but for many of them, there stats don't match up with what we see in the movies and tv shows. So I'll also be changing the stats as I see fit.
