Well, if you're just holding an axe, you generally hold it more in the middle of the handle so its more balanced. When swinging you obviously want to move your hands farther back so you can generate more momentum with a greater lever distance, but as an idle pose, the axe hand positions make sense to me. Though they probably stay in that position even swinging, right? Holding the dagger by the blade is the only really big offender of all the photos. The staff position could go either way. I think it's kind of funny how they shoot the magus projectile out like a cannon. While it would be cool if they used their staff as part of spell animations, it'd be a lot of work to make a bunch of animations just for spells cast when you have a staff equipped.
