You are correct. I guess I just kept skipping over that category. I did see on another website that this was discontinued in patch 3.2, so I thought it was just not updated here. My apologies.
I should note that all four of the items (Blue Ooid, Blue Roundstone, Bladeleaf, and Swordleaf) can be cheaply acquired by trading Steel Pirate Spoils from Trials of the Matron.
