You know you can get +8% movement pants by just doing the easy-as-all-get-out "A Shantotto Ascension" add-on. You have to select one of the three pants, but each one covers like 7 jobs. Since you seemed to focus on mage jobs, you can even get Cure Potency +5% to boot! So it may not be 12% from Herald's Gaiters, but it's something. RDM can use the mage one also instead of W. Legs. But I agree with other posters. W. Legs not that terrible to get now. Herald's Gaiters... that's just ridiculous.
