Since there are 4 "factions" if they do add bigger maps for more players, the no team option will allow them to play free for all matches.
They could specifically add variations on the game type in the server list, so that instead of just Multiplayer Campaign, it could be "Campaign - 2v2" or "Campaign - FFA", but if those are added, I'm not sure what's stopping you from playing FFA now. It's even possible to play 3v1.
Maybe in the future if there's enough demand, Larian could add in an 8-player mode.
You are missing the point though, the reason why no teams would be nice is because if they add diplomacy, eg.: making alliances during a match, making peace treaties etc. you dont need to use factions and the balance of power could shift, but if they only have 4 factions as it is now, any attempt to add diplomacy will fail, since if you are teamed up with someone, you cant make alliances and peace treaties with others. You will simply play out the match with the person you teamed up with.
Besides the obvious benefit for making free for all matches with 5+ players.
Also about adding infantry, i can see troopers when zoomed out and before they become icons fine, so idk what's with this need icons coz we dont see the units thing. which is why i suggested the increase in units becoming icons distance in the first place. Which means that i could probably see infantry fine as well.
Not to mention, you can always zoom in. You dont need to play the game from space.
