I'm sure I'm not the only one who noticed that we were able to obtain some T5 materia through the rank-up quests, but those quests are finite, and now we're all bloodsworn. This post made me think that there would be ways to regularly obtain T5 materia as a level 60. This was a big disappointment to myself and my friends.
