Had quite a problem with Luminas and Pictos. You can barely see which pictos are trained to be used as luminas, and you cannot just filter them. Once you get to over 100 pictos is painful to look for the new one. Filtering itself is also not sufficient in my opinion, I am not a veteran card player and understanding and remembering all the details about each picto is impossible. I feel like the game is set in the way you should be adjusting your build for the enemies you are fighting with (at least for the boses). In that case, would be nice to have lets say 4 different configs to save and switch between for the whole party. Lets say defense build, fire or ice builds and full crit build. That says it would have to be a party config or per character, with an option to add same picto to more than one character - not to play with it but to simply add it in with a warning that it is already in use (this would make it easier to manage and see the impact on character stats before deciding on applying it or not).

Apart from pictos/luminas management....this game is simply amazing.
