i cant say for sure but i dont think that exist on the armor part. i think there is something on the weapons when they are enchanted, like some sort of extra bonus for having a lower weapon with higher enchant value. but for armors i dont think something like this exist. either for now even on weapons is kinda pointless unless we talking about 2 weapons from same grade, cuz in such small diference the higher grade weapon will always lead to more damage cuz of shot bonus. this is for diferences like this one ofc, where the p atack difference is like 10. of if its a higher value it might start being worth to keep the lower grade weapon. big problm with L2 is that a lot of information they have in the game is not given to player. almost like buff description in c4 etc. "You are poccessed with the power of your ancestors" like ok but, what does it do exacly, no one knew. you knew u had a bit more stats and thats it and you char hited like a truck but you didnt know exacly what it was. same like this theres a lot of small stuff that some ppl never noticed so no one ever asked so no one ever bother checking for it so no one ever answered xD
