AV is not PVE, AV is PVP the entire objective is pvp oriented. Even if there are NPCs/quests and objectives the entire point is to compete against the other team which is full of players, hence Player vs player.
When the game is full of people like you who refuse to cooperate you ruin it for everyone else. How about you don’t queue for a battleground in the “Pvp” section if you aren’t going to assist in winning.
