Also it is designed so that if you are gathering Columi gear, you will be gathering/spending commendations on Tionese gear. Simply put, commendations that you will be acquiring will be for one rank down from the gear that you are getting as drops.
One more, potentially n00by question related to what I've quoted.
If both Tionese and Columni come from the same FPs (Hard Modes), how is it that you are acquiring commendations for the gear one rank down from what you are trying to loot? Should you approach the first Hard Modes you do trying to loot Columni and spending your tokens on Tionese?
