I as well am a bf vet. While bf6 has all the cool tech , it is devoid of the theme of battlefield. To answer the question "well what do you want" ,the answer is pretty simple. Take all that tech and put it towards a real Battlefield game , not Cod with vehicles.
**One example-Epic sized maps ,with the appropriate vehicles for the location. 128 players on those maps , a slower pace , non-linear capture points. 8 man squads , locked classes. land and sea or both maps. The commander mode on each side...good grief devs just go back and look and bf1942 , bf2 , bfv ,bf3 and the mods for them and hopefully you will get a clue.
But , as iamsharkx stated, as long as we are just seen as consumers and not a community..well..the word fail comes to mind.
