I had the opposite issue. Writing was agony and every section would be written, reviewed and rewritten to get my point across; only to be tortured by a miminum word count that was 20% away after saying all i cound think of saying.
I've gotten better at phrasing myself adequately in one go. Rute mechanical memorization has also made writing itself cheaper. (read my username)
I can now yap quite adequately over text, yet i regularly find AIs at a minimum 2x as verbose as my preferred phrasing after manual word mashing.
