Notes:
• (1) "Season start meta" refers to the commonly assumed meta in the week leading up to the season start, as communicated in public Diablo communities (in-game and elsewhere).
• (2) "Season end meta" refers to the meta that performed best at the end of the season. Note that both metas refer to high GR pushing, not speed farming.
• For top GR clears, the highest, fastest GR clear on the seasonal softcore leaderboard was taken (checked in-game on July 7, 2017 for up to Season 10); only NA/EU/Asia regions (no data for China).
