I have run into problems with my refined writing style, primarily because of vocabulary. I used “exacerbated” in a production report, which was a mistake because the manager was barely a HS graduate and it pissed him off. Sometimes breadth of vocabulary is a hazard: just because you know that and it is exactly the right one to use there, if it sends your readers running to the dictionary or giving up because you are just too intellectual, you have probably failed (unless you know how to couch the word in a sweet muffin of context that makes it easy to suss).
Also, I sometimes have a problem figuring out where to cut and run with a new sentence.
