I don't recall the following changes being announced during any patch, but noticed them yesterday, and so list them here.
Eorlingas Battle Lore and Eorlingas Warding Lore:
Old Recipe: 4 x Tomes of War Campaigns and 1 Small Westemnet Scroll.
New Recipe: 4 x Tomes of War Campaigns and 1 Medium Westemnet Scroll.
This change aligns them with the Eastemnet recipes, which have always required a Medium Eastemnet Scroll.
