To the OP - I am not condemning those clever people who are specialist web developers and perhaps in employment where they are given the time and support to specialise but if you are "pursuing a career in the digital space" and you mean as a self employed person then it would depend on what type of career you mean.
Also, if DW is producing a mess then perhaps you need to think about what version you are using and perhaps use it in both its design and code views. If you know HTML that should not be a problem and it can speed up the design process.
I am a self employed website designer. Making a living on your own is not easy and to do so I need to work quickly. I also need to have knowledge of HTML, CSS, graphic design, marketing, SEO, accounts, etc, etc. I am not clever enough to be expert in all of these. I am however competent enough to have been able to meet my clients needs since 2001. Probably the two most important tools I used during this time were DW and WW.
Added: forgot to mention researcher and copywriter. ;)
