So true. I served on a CG so we had the big advantage that our CO, XO and Department Heads were all second tour, so they had built up lots of experience. IIRC we had four or five second tour LTs that had sailed FFGs, Amphibs and carriers. So us new officers had the chance to learn from successful, experienced officers and of course some outstanding petty officers and Chiefs. As we got more seasoned and got a deployment under our belts, we got qualified and started taking over OOD, the older guys moved on to SWC/FWC or TAO to get them ready for DH school.
You had every opportunity to learn from the best. If you messed it up it was your own fault. Myself I was kinda weak in weapons and tactics, bad with comms, but considering my limited experience I was a good deck officer for a first tour LT. If I had stayed in, I'd have improved my weaknesses on my next ship.
