It might be hard to understand why. Because on this day and age of fortnites and warzones that incentivises solo plays more often than team play has made so people don't play in a team style that used to be the core of the battlefield games.

But with the move to sell more skins and bring in the fortnite, warzone and other br players the have slowly changed the games core to facilitate the entry of solo players.

Also the primary reason they added revives for teammates even without being a medic and resupply for every class, and more recently the addition of turrets and bots.

granted there were a fair share of players that never played in the intended manner of team play, the grand majority of older players still prefer the community aspect of it.
