can you explain what you mean by "action"? because I can't see what is lacking.
and the dead ends and WIP's are only that because due to one of 2 things, the first is that area's plot has yet to be developed and it could be an important place/it would not make any sense for us to enter that place yet. the second is that it's an unimportant place/event and will get an update but since that area doesn't have lore being added at that moment it would take away from time to continue writing the important stuff.
