I didn't edit out anything, I responded to the part I found to be relevant. If the projectiles hit the player things go from fun to not worth it and annoying real quick. I don't really use guns and think they are OP, let's remove those from the game as I have no use for them. You see the problem in that statement? You want something removed that YOU DON'T USE, in a SINGLE PLAYER GAME. If you don't like them on your PVP server all it takes is one small edit and that doesn't take as long as posting on this forum complaining about it. I complained about things before that "sunk in" for me too and enjoy the game a lot more with that newly acquired knowledge.
Some people are talking about this as if this were some MMO, it's not. You can turn up the difficulty and since you've NEVER USED THEM, take some advice from someone who uses them a lot and loves them. At higher game settings you are going to need a lot more to survive than those turrets unless you cheese the AI. They are not "OP", stop trying to have the stuff you don't use removed for no apparent reason what so ever. Everyone has their own way of playing, not everyone plays like you and since nobody is playing AGAINST you with these items I see zero reason for you to be complaining about how others play their single player game.
How do these turrets bother you?
In what setting are they OP? PVP, coop or single player?
