I couldn't agree more. We tend to make way too big of a deal over dovetails.
Here's my advise, for hand sawing any joint, not just dovetails. Learn to saw to a line. This is the single most important skill you can learn for improving your hand sawn joinery.
To get better at sawing any type of joinery, be it mortise & tenon, bridle, half lap or dovetails, you need to learn to saw accurately. Want to learn to saw accurately? Put down the dovetail and/or tenon saw and pick up a long rip saw. Take a 4' piece of 1 x 12 pine from the BORG and using a marking gauge, mark a line parallel to and about 1/2" to 3/4" from the edge. Saw the strip off with the rip saw, concentrating on tracking the line and keeping the cut plumb. When you have finished, plane the edge straight, mark another line and do it again. Keep doing this until you have a bunch of small strips (cross cut them and use them as stickers for your lumber pile). By the time you've sawn the entire board into 1/2" wide strips, you will have vastly improved your ability to saw to the line.
I'm convinced that the reason most folks have so much apprehension and/or difficulty hand sawing joinery is their lack of practice sawing. Most people use tablesaws and bandsaws for the "rough" work and do the joinery by hand. I think those of us who do at least some "rough" sawing by hand have an advantage when it comes to accurately sawing joinery because we simply do more hand sawing and have more practice sawing to a line.
I'm not saying anyone should go sell their table saw or band saw for a nest of hand saws . I certainly don't enjoy ripping tons of oak or maple by hand. However, woods like pine and poplar, which are popular secondary woods for things like case backs, drawer sides and drawer backs, are very easy to rip. So on your next project, try hand sawing the secondary woods for parts to size instead of using the table saw. It will give you practice sawing to a line for sawing your joinery but won't be an exhausting undertaking like hand sawing the primary wood can be. Plus, your cuts will be cleaned up with a plane so if they're not perfect from the saw it's ok.
I gaurantee if you practice hand sawing more often, such as hand sawing these secondary woods, your joinery will improve as a result.
