Well, the first time I noticed this, I did indeed have Mixed Martial Arts, but now I'm a Kensei / Evoker and lack anything of the sort while still using only 1 weapon and it still persists. And yes, it's regardless of my max durability. It just seems to always be 90% of whatever my weapon's durability was BEFORE upgrading it. Although, in the case of the Hahouken Masterwork Katana, it seems to go to 20 instead of 18 (18 Durability being 90% of 20 Durability) despite it's max durability is 26 (after upgrades), which completely confuses me given that 20/26 is about 77%.
