Oh, didn't realize they were going to be selling them each individually. I guess I was expecting character packs with like 4 minis (like Krosmaster) or expansions with a little bit of everything (like Descent) including new heroes.
I think an interesting way to sell these types of Character Expansions would be as "Guilds" of three or more characters. Small promos of adventure tiles and enemies would also add additional flavor. Full campaign books of course.
I do like the idea of getting multiple characters in a pack instead of just buying one-offs. I am hoping that there will be many more expansions/campaigns to come.
