Hey no worries. I understand that my reaction from back than can be interpreted as 'we keep everything and build on top' but that's not what I meant and also not what we were planning.
The reaction was based on the comparison between BFV's movement system and that from previous games. We were happy with the core movement mechanics of BFV. I mean stuff like ground detection, following the ground, moving over uneven terrain, vault detection, transitions between animations, stance transitions, cooldowns, etc. Stuff that made the movement feel smooth.
The mechanics that are mentioned above (prone on back, crouch sprinting, etc) were implemented specifically for the design direction of BFV back then, and didn't make it to this game for various reasons. Prone on back for example was abused a lot by campers and caused bad visibility, and crouch sprinting wasn't used enough to be worth the implementation and button mapping.
As this is a new game with a different dir...
