Sad thing about relic staff and relic maul is that they're *really* good melee weapons ... for jobs that should not melee in any important situation (like a big NM or Dynamis or something) that would benefit from a really good melee weapon. Ditto for relic dagger for two of the three jobs that can use it, and relic sword (or relic blade; whichever one is the 1h sword) for one of the two jobs that can use it.
In other words, if all that effort and currency had been put toward, say, someone else in their Dynamis LS who's a melee job improving a melee weapon ... it'd actually be worthwhile.
It's still quite the impressive accomplishment all the same, just kinda sad that it's a bit of a waste. They should've made the mage-only relic weapons give really good mage stats (like having all eight HQ staves rolled into one) rather than really good melee stats that just won't get the use they deserve.
