This might be one of those ideas that sound good in your head but probably would never play out well, none the less I've always imagined a no respawn type of game mode. And no not the failure that defuse was in BF4, but rather a game mode like rush where they're are two objectives or maybe a flag and it's no respawn 32v32 with vehicles. I've always thought that a full game mode with vehicles and no respawn would be one of the coolest things ever, only drawback I could think of is the amount of snipers that would be involved. This would probably work better in a game like BF3 or BF4 or maybe even BC2 but not BF1

Real quickly though as this just popped into my head, I've thought a game mode like war from COD World at War would fit absolutely perfect into a battlefield game, I'm actually surprised that war was only in World at War and Battlefield never adopted it
