I had an idea for how they might end All Out War a little differently. Neegan and his crew get defeated and killed. Many of the main characters celebrate their victory. But some others such as Gregory, Gabriel, and certain members who have suffered losses of family members seem upset. They meet and discuss the wide-scale death and destruction, and decide that those who caused the war to proceed the way that it did are to blame and must leave. They convince the majority of the remaining members of all 4 communities to back them. Thus, Rick, Carl, Andrea, Michonne, Maggie, (by extension Sophia), Aaron, Heath, Jesus, Eugene, Rosita, Ezekiel, and Dwight are exiled. Maybe Sherry and another survivor from the Saviors community go with them. After everything that's happened, there'd be some very interesting group dynamics. Not to mention the threat of being on the road with Maggie pregnant and Heath having one leg. I know I didn't account for the likelihood of a major death among Rick's group, but I honestly can't predict who might be the next to go at this point.

 

I was thinking along the lines of the survivors of all 4 communities blame them for it, and the majority demand they leave. Sort of like they're celebrating the victory, and then a wider view is shown and everyone else is upset at the deaths. They blame those who pushed for the war and led the way. I was thinking one of the leaders of convincing the masses to kick them out could be (spoiler of the issue released today)

Also, Gregory and Gabriel, who have both expressed disapproval of Rick's methods before.

 

I can see your point about them possibly being too strong to be forced out. Thinking about it now, sending a small group on the road again isn't really taking things in a whole new direction, as Kirkman said they would. Maybe they win the war and each take a community and start expending safe zones between them. Perhaps after all of those loyal to Neegan are killed, Dwight is placed in charge of Saviors community, with a member of Rick's group sent to keep an eye on things. Maybe Eugene and Rosita.

Maggie and Jesus run the hilltop, Rick and Andrea take Alexandria, and Ezekiel and Michonne take the kingdom. That way they can expand the cast at each place, and rotate between camps, slowly developing a much larger cast.

 

I hope Dwight survives. He's one of the most interesting in the comic right now.
