I'm noticing that Legendary items often have significantly better stats than Legacy items. This feels kind of like a broken mechanic.

Legendary Greatsword (L163+81) - Strength +6800, Intelligence +6800, Cold Resist/Block Chance, +41% Animal Damage, Damage +1873

Legacy Greatsword (L214) - Strength +2568, Intelligence +2568, Agility +2568, Damage +1643, Damage +6%, Speed +10%

The Legendary is clearly significantly better. Maybe a fix would be to allow legacy items to be upgraded.
