Spawncamping - Why isn't more done?

Hi all, So just a general open question really. Spawncamping is quite common in this game (especially in RB Ground) and a lot of the time this is because of poor map design. I don't understand why the snail hasn't done more about it? To be clear; I'm not talking about times when your team has captured all the caps on a map and have nothing left to do. That situation is completely justified and a normal part of gameplay. I'm referring to the times when your spawn is clearly visible from 3km away across the map and prevents your team from making any progress due to one or two players being able to shoot directly into it. So much of this can be avoided by better map design and larger "no-go" zones. I'd be interested in your thoughts!
