For the small number of fights I actually still kite as a PLD, these legs are insanely useful. In my shell, PLDs and RDMs get a slight priority on these, but it's all point based, so if you work hard enough, it doesn't matter.
I went something like 1/16 Kirin fights where I was first to lot, and something like 5/50 fights total on droprate. Seems like it's about a 10% droprate for the W Legs Abj... :-/
I must admit though, these almost never come off unless I am straight tanking something fairly difficult, or fighting a demon type mob, or a mob with the Dragoon job.
As a unexpected side effect, I have also saved a small fortune on sneak oils. As a PLD/NIN, I can get to Fafnir with a single oil, and can get to most places in sky with no sneak oils at all. Being able to outrun almost everything and working the portals fast enough makes it possible.
Side note: Is it still possible to intimidate yourself wearing these assuming you have an item with the Dragon Killer ability? I have been told yes, but have been unable to do so with the few tests I have done...
