I do appreciate this type of analysis having a civil back and forth discourse with the mathematical rigor behind our staements being transparent. The philosophy behind assuming 50/50 between accuracy and kinetic/elemental is to create a build that is well rounded for any encounter you might face (some bosses have all/no tech and some bosses have all/no elemental). Obviously there is an optimum build for each boss if you take their accuracy into account, however, you cant really build to compensate for internal/elemental... except for having a HP/heals build over a mitigation build.... which is still a rich debate.

i still think that the 85% downtime of the healing relic, as well as the overheal, are somewhat good arguments against using it.
