There is that one thing I always wanted in every BF game: destroyed vehicles not disappearing
I think it's always been a technology limitation issue, and I don't care about soldier bodies, because that can become a mess... But one of the things I always wanted is to keep destroyed tanks, choppers and aircrafts on the map instead of disappearing after a few seconds.
Other than immersion, I think it makes for a nice gameplay element. Using them as cover for infantry, changing how a map is played and such.
Could we finally have the technology? I would love to see it in BF6. Even if it's a limited number...
