On to the second point, the EW Relic requires no effort. I get it immediately after Hildabrand since The game throws Tomes at you for benign and easy stuff like Rouletting into Satasha or Crystal Tower and you can hold tomes until then. The way they handled EW relics completely misses the point of Relics in the first place but even if the devs truly wanted current Relics obtained by player choice, there was certainly better ways to do it.
