A lot of the builds, minus the Bravura build, have lacked a substantial amount of Accuracy. I was recently forced to gear WAR for Provenance and found my Accuracy to be terrible. I had to gear it in a hurry and managed to leave some crap in my Mog House, but my meager attempts at cobbling together an Accuracy build were not pretty.
I was already considering putting a Ragnarok build together, but was curious about builds geared more towards those fights.
