A couple of things. First off welcome to @Helmut and congrats on your first post.
Second thing, Levolution is going to be (in my opinion) the thing that trusly differentiates the Battlefield franchise from it’s competitors. I am looking at you Call of Duty.
If they manage to pull off truly destructible maps, it would mean that every single match would be unique. Imagine knocking down a bridge so armor cannot cross, however the bridge can be repaired.
Or knocking down a building strategically so that the enemy are forced into a funnel, where they can be mowed down. With infinite destruction, brings infinite map combinations.
