Can i buy Relentless now with Emblems of Triumph?? or Honor? Soz for the newb post!

If your talking about when the new season comes will triumph buy relentless, then no. Each lvl of badges usually buy the proper gear, so most likely relentless will be bought via emblems of frost, and triumph will remain at the furious lvl.
