Queueing into any of the Hildy trials on Materia DC is a huge pain in the neck due to how few people have them unlocked. Requiring them for relics = more people will unlock them = more people will get them in Trial Roulette. This is a win in my book.
(Also, the ARR Hildy quests may have been tedious and annoying, but the HW and ShB ones were Solidly Okay.)
