Don't know about floating wreckage in the BV (but wb cool) but they have said they might have salvageable wreckage after the battle in a future update
Well that`s something, but whenever i`ve watched sci-fi movies, I`m always more interested when i see lingering wreckage during the battle. It adds to that feeling of epicness. I don`t know how to better explain it, just watch any sci-fi flick where the sparkling wreckage of part of a spacecraft in battles floats by instead of just vanishing.
Please consider this, Devs. Even make it optional if you`re worried about it taking up computer cpu\ram resources.
