I worked with lawyers, 0 RFEs. In the last few weeks, I've seen a couple of instances when a good lawyer would add value instead of users clearly struggling to comprehend straightforward guides and instructions. Lawyers are not needed in every case, but what I've seen was hopeless. I don't want to name one user, but their family got in removal proceedings because they couldn't follow the process. It must cost them a lot more now than paying a competent professional to file their case. DIY is not for everyone, sadly.
