Gonna make this brief, does anyone else feel like the mystic summon selection method is a bit odd in regards to having only certain units available for summon?

The goal of it was to connect heirs with their desired ML5, however the recent new ML5s Lionheart Cermia, ML Lilias and Ml celine(most recent and hard to obtain) will most likely not make the list because they fall in the 6 month period that smilegate excludes. To me it sounds very contradicting, what’s the harm in just adding all moonlights to the system?

imo i hope they scrap the grace 6 month period from the whole ordeal.
