I love my current weapons and armor set and I don’t want them to become irrelevant. Not that I will exclusively use them in Y2, but I’ll always want to come back to my Midnight Coup and Took Offense armor.
I’m sure going back and adding perks to Y1 gear will be a pain, but it will make all of Y1 feel worth while if I can still use the old stuff I’ve worked for in Y1 and kill some new baddies while using it in Y2.
