Detail
Column positions and arrows appear explicitly only in talentsforever.com/data/druid.json. Tier (row) assignments match foreverchanges.pro and page order on several calculators. classicwow.gg and wowforevertalents.com pages rendered through a text fetcher gave different columns and arrows (e.g. Moonglow on tier 1, Wild Growth on tier 6), but those look like extraction errors. MythicSim independently says HotW moved to row 1 and Moonglow to row 2, which matches talentsforever.
