In BFV if you're in a vehicle you can jump to any other seat in the vehicle instantly.
In BF1 at least in planes you had to exit your seat, walk across the plane, and enter the rear or front gunner position.
Is this going to persist in BFV? Instant seat jumping? Right now there is absolutely no negative effect from being a bomber pilot and jumping to the rear seat to shoot down a fighter because it's instant both traveling to the seat and back to the pilot controls.
I understand the bombers are longer than the bombers in BF1 but at least give it some travel time. It's absolutely ridiculous atm.
