Since we get besides jobs also class only gear , we also need all sets of non job classes set as keyitems.
So basicaly u ask that every high level gear in game is to be set as keyitems.
aint gonna happen unless it's special gear like AF or Af/class only gear.
That means that all weapons ifrit / moog etc would also be keyitems , since u have for every job/class 3 weapons / ifrit/moog and garuda and soon more with new bosses comming up
