IF your style of lineart is comic/manga like tier, that's also hard to do, giving life to the sketch 80% on lineart. Here the render is secondary, because you are basically taking the sketch as a template for the finished work.
If you are just going to full render it lineless or with very thin lines, then lineart is also monkey work because it's basically tracing the sketch 1:1 with a smaller brush.
