KMST 1.2.470 - New Character sets?

I am surprised they used new designs for these lvl 145 weapons. I mean after reusing the reverse weapons design so many freaking times, its weird they didn't use the level 140 weapons' design.

I'm totally guessing but, what if the "joker" property of these items allows it to fill the weapon slot of any set? As in any set recognizes these weapons as the actual ones that belong to it, giving you a higher bonus of course.

I bet that'd make them wanted.
