Why cant Wizards use xbows, they are smart enough to conjure magic...yet they cant pull a trigger on a bow?
It's not even like they would have to use it. They'd just go like 'Man i have no idea how the fuck this thing works, but apparently my Blizzard is way stronger when I hold it!'
I actually love the design decision of basing all the skills' DPS on weapon, but yeah, from the 'realism' point of view it is a bit ridiculous
