Back in Halo 3 and Reach, there were Heatmaps on Bungie.net where you could view both global and personal deaths. I believe they continue this for Destiny still.
I think these could could be a great addition to Waypoint for Halo: Infinite. I always used them to identify bad habits as well as have a chuckle at the mysterious small dots placed in unusual places.
I loved heatmaps! Watching them develop as I played was always interesting. I never thought to avoid the places I died repeatedly; probably would have been a good idea.
