Yunna's O3S vid is good. Aside from the scythe tether being taken to the wrong direction, as you want to always end up mindjacked in a diagonal-direction from your tether

I do like the Dissipate spot right before the animal game if you need the stacks. Although this can potentially take your swiftcast out during the last phase period where there is likely more-derp. It's a basically a dead spot for any damage, but it is notable to get more stacks freely.

The fairy tether is pretty valuable in several places, since it allows more healer DPS uptime for both. Especially the tanks that take an add by themselves. Of course my PLD does run the fight mostly in Sword Oats, and autos and mechanic damage I really don't have to babysit because of it. I'm sure this will change a bit as the weeks go-by with more gear.
