The patch notes keep on updating. Rygarius just tweeted an update, and while there's not a ton of changes, some of them are pretty interesting.
- There's now a Blacktalon Quartermaster in the Tavern of the Mists for players who need to get a previous legendary quest reward (such as a gem for a Sha-Touched Weapon) for a new item.
- Several mage changes - Blazing Speed drops to the level 15 tier (with a whole lot of changes to the tooltip, it seems), and Flameglow, a new talent replaces Blazing Speed at the level 30 tier, and more. Scorch is now baseline, available to all fire mages. There seems to be a significant amount of reverted changes here.
- Light's Hammer now applies a 50% snare for 2 seconds.
- Evangelism's stacking buff now applies to Penance as well.
