While I've never flown in Whiting (for the record, I've heard it's TERRIBLE especially with split field ops/WAY more planes there etc), I can tell you that ATC (being students here as well) sometimes just plain SUCK. I've gotten countless relatively small errors (turn RIGHT to a heading 20 degrees off my left when they DID NOT intend for me to do a 360, fvcking up clearances, clearing me for something, then yelling at me because they "didn't clear me" for that), but I've also had, once or twice, SERIOUS errors on their part. On an RI hop one day, I was putting the bag on after the gear came up and saw a C-12 flying off our nose. He was JUST cleared to turn left on climbout from the right (parallel) runway. IP maneuvered to avoid the collision and informed tower that they cleared a freaking plane in front of us.
Whiting may suck, but Corpus isn't exactly "safe" to the point where we don't need a useful NACWS. But again...this is just my silly ENS opinion and the guys with the birds and stars on their collars are the ones that make things happen...
