Observation about recent wake island trailer and devs perspective of what battlefield should be

So I was watching the trailer for the new map and I noticed something, the game looked like classic battlefield fun.

Aside from the obviously scripted sequences, you don’t see anyone sliding and jumping around like you do in actual multiplayer.

So the devs created this whole scripted sequence of what battlefield should be and they know not to put the bullshit movement they have in game in the trailer.

So my question is why is it in the game? Who are they trying to please here, and if they are trying to please a certain audience with this movement, then why not include it in trailers?
