The issue with not having turrets is that its extremely difficult to get research for blasting charges up quick enough, and for Cassandra Classic and Kassandra, the difficulty ramps up quite quickly that you can't get good weapons quickly, nor do you have lots of people ready to kill enemy raiders.
I wouldn't advocate a complete removal of turrets, but they need to remain to give you a good chance early game.
