I was gonna say pass on defender only trash by default, but since you don't have Kyuuki bow apparenly, you can equip the collab sword if you need the HP. My understanding is that wind won't get any more viable event weapons with defender until Garuda 2nd reprint next July.
Although, where would you need more HP? My wind team has less base HP than yours and the collab sword won't make a difference for me.
