balacing out the number of members per squad

Nothing is more annoying than being SL4 on the point you're trying to cap and provide a spawn point for your TWO squad members, while SL1 has 15 squad members and is who knows where. I can understand having a lot of teammates in squad one when there is only one squad leader, but if there is 3 other squad leaders why do most end up in the first squad?



Also, for some reason if I join late I sometimes end up having no squad leader. What's up with that?
