That is why I went with BLM as a my main even though I have RDM at 70 as well. It came down to materia on which one to main because BLM need Spell Speed while my RDM doesn't. Granted if DET proves to be better then crit this time around, I could use my RDM some times. For most things though since I went with SpS, I am sticking with the BLM.
