So my first question is about weapon badges. Where can I turn them in for actual weapons? Or should I hold on to them for later levels? I'm only lvl 20 ATM.

Also I'm playing a Braver main. What is a good subclass for him? Hunter? Or something else? I plan on using katana mostly.

Also is there a way in the options to change the window sizing at all? For some reason I lose about a half an inch of screen on all sides when I play. Thanks for any and all info.
