I know it's not what you're looking for, but I support tracing, to a certain degree. I got my start by tracing various super saiyans back in Elementary school, and then I'd go and try to do it without tracing.
Basically tracing is like training wheels, and it's a different form of practice. It lets you feel what other artists are doing, instead of trying to see it and copy it. So to put it nice and simple, tracing is a good way to up your confidence, and learn some new stuff at the same time.
The only downside to tracing, is that you often pick up bits and pieces of the artists work. Every character I drew looked like it was straight out of DBZ for years after I developed my own style. Another thing is that you can get attached to tracing, that's when it gets bad. Don't get attached to tracing, whatever you do. It's only meant to point you in the right direction if you're lost, new, or just trying something out.
Tracing is good, don't abuse it though.
