No duck diving while swimming?

Maybe I’m doing something wrong? 

Tried a dip in the pool on the new map for crits and giggles and to see if there was some sort of achievement.  While I was in there I started taking fire. Instinctively I hit the B(crouch) button to duck underwater like I do in BF4 and BF1 then tried to switch to pistol. NOPE. No option(Hit B to dive) on screen either like we see in previous titles. 

Really DICE? Have the Devs and producers never played the maps Paracel Storm or Flood Zone in BF4? Hell even BF1 and BFV have duck diving. Sure it’s just the swimming pool but in BF6 we should expect big maps with lots of water  and boats ala BF4, BFV and BF1. 

 In 2025 we should expect more and improved abilities from the BF franchise. Not less.
