I don't think they're that bad or even bad really.
I kind of like them, but the theme seems a bit random. Like from 3rd stage to 4th stage a lot of them feel like they become completely different weapons. Not that this doesn't happen with older relics(usually 2 stages before last), but in a lot of those cases it's because the relic you built up to that stage is essentially destroyed and reconstructed. The lore from the mandervilles isn't really that fresh for me though.
BST is a limited job. It's going to be like BLU with no relic weapon for it most likely.
