Hi, I have been testing both but still couldn’t decide. Both Echo and Azure were primals with almost similar main stats (10% dmg and 24%AD), Echo has an additional IAS which could be rolled off to something else, but Azure has 20% cold and 25% chance to freeze which works well with Relentless Assault. Both have nice affixes which helps a lot in dps too.
Just curious, which one would you use for speed 2.5 mins GR runs? Thanks!
