Out of game accessible combat log

I have been working on creating some builds of my own rather than just following guides, and have noticed that there are quite a few places where it's impossible to evaluate the build based on anything but "feel" because we don't have the required data.

Some examples:
* Infusion sustain for CoC Comet. I want to know what % of Comets are fire infused
* Mana sustain when using remnants. I want to be able to track how many remnants and infusions are generated vs the mana cost of the skills generating them.
* Real usage rates for skills, especially triggered ones. Invaluable for knowing how much they actually contribute to your damage.

As such, I want to request a detailed combat log that is written to a file or similar (e.g. a configured endpoint) so that it can be accessed out of game. For my use-case, it would need to include:
* Each action taken by the player, e.g. use a skill, triggered actions, etc
* Any interactions of that skill, e.g. consume a charge/infusion, generate a charge/infusion, crit
* The damage done by that skill
* Basic info about the enemy, e.g. resists, armour
* Player buff/debuff deltas, e.g. gaining or losing an effect and why
* Player damage taken events, ideally but not necessarily including mitigation info

They've ignored this request for over a decade. Good luck.
