Once a map is public, you cannot just change it anymore.
I think there is a misunderstanding here. You can edit a map that has gone public and submit the edit to go public just like the initial 1.0 ver. The only thing you cannot change is the map's name. Everything else is fair game, including adding or removing territories and bonuses.
Edit: also here is a link to the Warzone Map Making Discord server, if you were interested. Lots of people that can help in there. https://discord.gg/yZy9AjAY
