Is something more big in term of scale planned? Some gamemode like frontline that advance with the map with point to conquest in a big scale mode? Map feel to small with this gunplay, wouldn’t be the point of having a big mass of soldier ? Why dont increase the map used instead of a little sector like now?
The developers promised “hundreds of soldiers”. As it stands now, we can have up to ~13vs13 or 26 players in a squad battle. Each of those players may control an AI squad of up to 9 soldiers. That makes 26x9=234 total soldiers. The scale of battles is larger than you may think 
Already suggested as well

Yes, but the map feel to small for now
So it Is suggested but nor planned?
People have been asking for this forever, myself included, but I really don’t think it’s coming any time soon man. I initially thought the small maps where just for the alpha and beta tests, but I think it’s a way for them to make multiple missions for the price of 1 map and moreso a cost saving measure. Who knows though, maybe someday we’ll get a full map gamemode.
