Streamed during the 2023 Las Vegas Fanfest, the 78th Letter from the Producer Live covers changes that will be coming in patch 6.5.

As with other X.5 patches, this one will be released in two parts. Patch 6.5 will release in October, prior to the London Fanfest. PvP rebalances, along with the next PvP season, will be coming in patch 6.51, after London Fanfest, to make sure the Crystalline Conflict Regional Championship for Europe is not impacted. Patch 6.55 will be coming in January after the Japan Fanfest.
