Just how much of a difference do you think editing makes to the quality of your final product? If a person sucked at editing, how adversely would it affect their efforts to put themselves out there?
The performance matters most, you can edit something to perfect comedic timing or have a gorgeous soundscape, but if the acting sucks, then it's going to show. I wouldn't worry too much about it if you just want to be a voice actor, someone else will be editing your performance.
