Critique and Advice; the treadmill of adventuring.

I think the issue with time travel is that 90% of the time I see it in a story it's thrown in because time travel is cool not because time travel is needed for this story. Time travel is also confusing. Such as, if you as the author realize you're having a hard time keeping up with your time travel situation / have 4 pages of notes to keep yourself informed on how time travel in your setting works then consider how lost some of the readers might be. I have very little idea how time travel works in ANL even after it was explained, in fact I was a little more confused.

Like everything time travel is useful in situations where it works with the story instead of it being tagged on as something neat and shiny.
