I won't be able to get to it until next week so I'll tell you what needs done to update this blog. The link provided in my above comment (calc. data) has all the dragons and their rarity type. All that needs done is to look through the data and record what each dragons rarity is. Once that's gathered this blog can be updated. Although I think I'm the only one who can update the blog due to it being another users blog but gathering the needed info is the biggest part.

So, if you feel like gathering the info you can post it in the comments here, on your/my message wall or create a blog with the info and then I'll just copy past here. Again, that's only if you want to.
