It really doesn't matter. At 45, you'll be wearing AF stuff in most slots, and whatever you put in body and weapon are really going to be fine. If you're worried about your weapon, you should be able to get a Vintage Bill on the cheap when you hit 47 and can use an ilvl46 GC axe at from level 44 to 46. Don't worry about min-maxing secondary stats at all until you're ilvl70+ and heading to extreme mode primals and BC.
