I looked at radiant incandescence. It was missing multipliers from the core passive and mastery - I’ll update that. Not sure how that slipped through… weird.
The raid healing rotation doesn’t use ever-rising tide on cooldown because it ends up being just as effective in that script to save it for big damage phases. The amount of healing needed between big raid damage isn’t enough to make using it that effective. It still simulates as the best essence by a fair margin. The mythic+ script uses it on cooldown because there is more consistent damage.
