I couldn't agree more.
Please check out this concern voiced by Anne Seaman:
I find this to be especially true on MAPS where I may have multiple plots (plus background lines, etc) and a few in BOLD.
The background points become too faint for my old eyes to even see
If you feel similarly, please consider upvoting Anne's idea. You may also expound on your issue if it's not the same.
Thank you for the comment/support. Brand new users may not notice what is a significant difference in versions and the uses of Tableau live or printed. In addition to hard copy publications which is a very important issue if one is to create a PPT deck or PDF. I use the best tools available to create/render images but you cannot remedy a problem when the source is the issue
