Make good maps.
Look at every 2042 original map, those are all bad. No soul. The only good maps in 2042 are those from older games.
I would recommend picking a certain region on our planet and build the game/story from there. (2010 medal of honor did this amazing) Make maps realistic according to towns/cities, fauna&flora found in this region. It will give the game an identity, a more realistic and coherent feel and this way you have room to create something unique with every installment.
Now we get an ice map, a jungle map, a desert map, a city map,... It's not coherent, its all over the place, it has no backbone. And what are we going to do next game? The exact same thing?
Also downsize the number of players according to the number of objectives. In a conquest game with 5/6 objectives 32vs32 players is maximum. In a rush game with 2 objectives in each sector, 16vs16 players is maximum. I think bf3 was even 12vs12, and this is considered the best rush gameplay in battlefield history,... something to think about imo. I wouldn't mind going back to 12vs12! This will result in a slower pace and a less chaotic/more realistic feel of the game. Nodody ever asked for breakthrough... It doesn't work.
Also really important when creating a rush map is to make the maps wide enough. Give the attacking team enough room to flank the defending team. Different ways to tackle the objectives will encourage squad play and this is where the fun lies. Come up with a plan, execute, push through. Sure bottlenecks look really cool, but in the long run they get boring.
So to recap, realistic settings (like a real village, a real harbour,... nothing that feels created specially for a video game) natural look, wide enough/enough room to tackle objectives, adjusted number of players, slower pace.
First make the map from a real life location, after that start thinking about where to put the objectives and maybe adjust a little bit. Noshar canals is an awesome map that does this great. It doesn't feel like you are on a video game map, it feels like real location.
