Black Mages, point the way to darkness! (relic question )

[Flipside101]

Is there a significant difference with SS over CRT?

Here's a question: Would you like to cast things faster and more reliably while moving during mechanics/aoe heading your way, or rely on RNJesus to give you those big numbers? Now if you're comparing DET vs Crit, would you like to have more "crappy" int, or (again) pray to RNJesus?
