the boots are max agi and the belt is max agi. the only reason to use the boots is on a guardian druid or brewmaster monk along with the defias belt for the set bonus. if you're using the boots on anything else it'll just be for 'swag'. I also read somewhere that full defias set is max agi (with chest piece) so maybe useful for a toon with defias chest like a rogue or hunter or feral. (please don't play a feral)
full defias is bis for non gloom/thralls gift twinks
Out of curiosity, what does thrall's gift change for full defias set? Bracers aren't part of the set so why would it matter?
Defias set twinks don't have thralls
Couldn't you race change to goblin to get it?
