I'll use it on t4 during last phase just to help out a little and on t5. Ifrit ex if things are a lil shakey around 3rd set of nails. Other than that I think the only place I use it is on titan ex during heart phase to help DPS heart so we get no bombs. I also use to use it for caduceus at split, but w/ so much more gear now it's not really needed. Could definately use either some tweaking or reduced timer. As most people say, it can help but it's USUALLY not a wipe saver in the same way that benediction is, but on the same CD.
