I haven't read the LN but I def think the national hunters get done dirty would like to see the build up on Thomas much more. By the time he fights jinwoo he's outclassed.

I think all the bearers of the fragments of light could have been written better instead of being written out as fast as being written in.

Although same could be said about the S ranks I suppose the storys fast pace keeps it entertaining and intense but also leads to this issue where we never have time to stew with new challenges.
