I’ve taken your approach as well but I did notice that I retain Kanjis that I learn to write significantly more than ones I can just read. But memorising all the Kanjis is a bother.

I found the sweet spot to be writing on a scratch pad as I go through Anki. And not particularly worry about getting writing right too much. Sometimes I’d be confused in my head but my muscle memory would kick in and automatically write the kanji!
