The rally point (a.k.a spawn beacon) is very important, spawning behind the enemy, flanking, etc.
I dont know why squad leaders seems to refuse to use this feature, maybe 99% dont even know that this exists, it takes about 2 seconds to place one and some players are too lazy to place them.
Should be a hint for squad leaders to place the rally's or move them to the sniper class like Battlefield games.
