Are the EW Trusts separate entities from the ShB trusts? Do you level ShB Urianger from 71 to 80 separately from leveling EW Urianger from 81 to 90? Do Trusts instantly upgrade to Lv81 upon unlocking the Lv81 dungeon for the Trust system even if they're still Lv71? Do you have to level Trusts all the way from 71 to 90 if you didn't get them to 80 before unlocking the Lv81 dungeon for the Trust system?
Nothing I read answers these questions and my archive footage from the early EW days doesn't seem to include any of my Trust plays prior to having everyone around Lv89.
