Idol — one of the subtypes World of Warcraft files under Armor — gets this table as a focused view: the same drill-down the in-game Auction House browser applies when you filter by subcategory.
Because this table is filtered to Idol only, it stays short even when the parent category is large — a fast way to scan a single subtype without paging through unrelated items.
The "Browse subcategories" links on the parent Armor page list every other subtype if you want to compare markets side by side.
