I think the true crux of various issues this game has is simple, it’s size. Most objectives are small cramped buildings or just have very little space. It’s extremely easy for the enemy to just zerg into one building, or for tanks to spam one building, or for planes to rain down on one building, or for flamethrowers to clear one building, or for Assaulters to clear one building, then BOOM the match is over in seconds
Not to mention various other features in this game that are not realizing their full potential. Sometimes there’s not really a point for rally points when the distances you have to cross are so short. Or vehicle variety, the meta leads towards the heavy tanks that can “tank” everything because you are only ever facing one direction whether attacking or defending.
But if the battles and objectives are much larger, then it’s not so easy. Battles would be more of a struggle. Battles and gameplay would be more dynamic and fluid. A Giant Battle would solve many gameplay issues as well as many current gameplay features realizing their fullest potential
Both teams only have one HQ spawn, making distance important. Rally points would be more strategic and important. APCs would be even more useful as mobile rallies.
Objectives are much larger. Instead of a single building, you may be fighting over a whole sector. Fights for objectives would be a struggle for both sides. With a fully open map combat would be more fluid as you would have opportunities to flank from different points. Not to mention that in larger objectives there would be various locations being fought for all within one objective. The strongest weapon types wouldn’t be able to easily zerg the objective because objectives themselves would be much larger. Sure your SMG can clear a single building, but that building is just one little piece of the whole sector you’re fighting over.
Vehicle combat would be more fluid and dynamic. Effectively there would be no Gray Zone. With a fully open map with multiple objectives your vehicles have to hoof it to the battles. Flanking would actually be viable because vehicles could charge into the objective from any area. Vehicle classes would be able to fulfill their intended roles. With an open map and large objectives a light tank would shine speeding around and flanking infantry within the objective sector
Mines and Engineer constructs would be more useful. Hedgehogs, barbed wire, MG nests, etc would be more vital as with a larger map it would be strategic to block specific routes. With the battle being open with enemy movements everywhere mines could be placed anywhere.
Paratroopers would be more strategic and could better play their historical role. Parachuting behind enemy positions, building rallies deep into enemy territory, ambushing and stalling the enemy……instead of spawning just a few feet more on the frontline than spawning on the ground
A pipe dream of a Giant Battle would be larger teams. I envision 50 vs 50 squads, with at most 30 infantry, 10 tanks, and 10 planes. Having more players would increase the variety of your team’s arsenal. In the game’s current mode classes like Medics and Mortars are niche but with many players your teams would at least have every role covered
More vehicles would add more variety and various roles would be covered unlike the base game. Heavy tanks, medium tanks, light tanks, armored cars, tank destroyers, SPAA, etc would all be able to fulfill their roles.
Sometimes plane gameplay can be a little boring when you want to dogfight but the enemy team isn’t fielding any because there are only 10 players and no one may want to play as a plane. Well with more players chances are there will be many players who want to play planes. Every base would be covered. There would also be enough players who would man AT and AA guns increasing that dynamic in gameplay
The maps as is in game are already large and would probably work perfectly fine in a Giant Battle with some tweaking. But new giant maps certainly could be made, even perhaps remaking current maps giant
Conquest would work well in this kind of mode, but Invasion and other modes theoretically could be overhauled to work in a giant mode as well. Even a mode like Conquest Assault like from the Battlefield series would work
