People here complaining about the stats need to realize that this stats are perfectly valid once you take into consideration the other i210 options.

The "Bad" relics are only so because these classes already have good Upgraded Eso/Gordian weapon.

BLM's get CRIT/DET on their relic, because their alternatives already have CRIT/SS and DET/SS combo.
NIN's get SS/DET on their Relic, because their alternatives already have CRIT/DET and CRIT/SS.
DRG's get SS/DET on their relic, because therr alternatives already have CRIT/DET and CRIT/SS.
PLD already has a CRIT/DET option.
SMN same deal
etc

On the other hand, classes with shitty Gordian/Eso get amazing Relics. WAR, DRK and SCH come to mind.
