What? In AV, you can guarantee that you engage the enemy.
For example, I ensure the horde has a hard time capping SH bunker when I play there. Not because of archers
, but because I get there and kill them as they dribble in. If I get killed, I get rezzed at SH GY and interfere with IW B, or I get rezzed back north and go defend DB.
This sort of defense is something you rarely see on the horde side. It's a big reason why alliance zergs so often win: they aren't pure zergs, but have a significant defense component.
Sometimes, when I really want mass PvE in AV, I convince people to defend Balinda. Last time I did this we got a reverse turtle with the horde bottled up south of Tower Point. Good times (and someone on the team got the AV Allstar achievement.)
