So with my proposed reading order, I decided to focus on characters and events. While it is generally in chronological order, I didn't like how character arcs are interrupted with other stories and how long it takes for the story to return to said characters, because my memory is so bad. I personally read it in release order and I find it pretty sloppy and all over the place. I have finished most of the Horus heresy series, and thinking back, I wish I knew then what I know now in what order to read it.
