yea my problem is not with the difficulty its with the design .
1 let the players actually trigger the shots
2 give the turrets a dismount button so you don't accidentally get off
3 Turret movement may be to sensitive, I run with my mouse sensitivity pretty high and the first time i used a turret I was all over the place lol
4 and make the actually shooting more smooth the shots seemed very random i.e sometime it shot fast then others seemed very slow
