Its basically making all our weapons we grinded for obsolete. At least retroactively apply origin traits to adept weapons for all we did to get them.

I dont think it’s necessary except for with adept weapons, since they are difficult to get, so it would be a pain to have to grind for the same ones again (and if you care about adept weapons then you probably do care about the bonuses from origin traits, even if they are small)
