I wanna start using Watson, any tips or main things I should be using / taking advantage of?

I been using Watson very recently to try getting a feel for her character along with deciding if I should main her next. I honestly decided to main her but I wanted to ask this subreddit if there anything I should start practicing or getting used to doing as I main her and get better with her. My main goal is to like achieve a 3k badge with her currently or like thousand total kills on her legend.
