Ritual Tablet Drops: Monsters in ritual drop precursor tablets (?)

Please revisit the drop rates or constraints around Ritual Tablet drops in maps. They seem exceedingly rare compared to other tablet drops in endgame. Ritual Tablets only seem to drop from monsters in the ritual circle before the ritual begins. Monsters killed during the ritual will sometimes drop Precursor tablets. Unclear if this is intentional. AFAIK monsters killed during other content only drop tablets of the same content, i.e. breach monsters only drop breach tablets etc.

Consider adding tablets to the ritual rewards, adding an atlas passive that increases their drop rate, or simply adjusting the drop rate to make ritual more sustainable in endgame.
