Thanks for the reply. I read it but I didn't get much information how to improve the campaign itself. But sometimes that is not necessary. You just increases my motivation towards the campaign and gave some thoughts I needed.
It is hard to give such an accurate review at this point of campaign where only 6 of 10 chapters are done. That is very understanding especially for the story part: the big secrets are told in the end of the campaign such as Fradz's story, secret characters and what part different dragons play in the story.
Anyway, thanks again.
