D&D General dnd character ability ... formula/power rating?

[unan oranis]

Has anyone made a formula/power rating system or something like that to build your own classes and abilities? (for 5e)

The advice in the DMG is nice, but it basically amounts to eye-balling, and specifically says "there is no formula" - but is there?

Some crazy dnd person hacked something together, surely?

There's a ton of stuff that would be difficult to quantify of course, but I was hoping someone took a stab at it or there is a resource I'm unaware of.

The best attempt at this that I have seen was L'arsene's Ledger of Treasures and Trinkets (specifically Chapter 5).

This was for Magic Items not character abilities, but presumably the hardest part would be implementing such a subjective rating system in general, not really the part of converting from Items to Abilities
