So I imagine it's not a "new discovery" but I found this cool:
Spoiler: show
Can LoS the tail swipe and still be in healing vision of tank, for ultimate lazymode. Adjust for whatever minor rotating your tank does in a particular instance. Did this on WHM as well, standing where the fairy is (though then you have to move to be able to nuke boss).
Also found out gil drops from dungeons are split between the 4 party members. I did the "log out in an instance" trick after a finished WP to friend my alt and went back to the chest before first boss that spawns beetles. Holy'd them down, got ~200 gil apiece.
