So before I did mention 3 teams and 2 solos was because of that being what the X corner had at the time, so a condition to work in. But it seems though if in control a shorter story would work better which yes I do agree.
I do believe Marvel should start books like tv seasons with writers getting 12 issues a season and around the 8 will be the deciding factor if a book continues.
But yes if in control I would have a main Inhuman story in Graphic Novel style of being just a giant block, with side stories and spinoffs being told in minis.
As for Luna in tumblr someone was shipping her with Franklin RIchards and had this why:
