Hello! I managed to fix my broken DS and decided to start playing this game.

So, every time I play a RPG, if there is an option to make a bow/gun character, that's what I always go for. I would like to go for that kind of build for this game too. The problem is, this game has a lot of depth into it when it comes to characters, classes, weapons, etc. and to a newbie like me, it can be a little overwhelming. Can anybody recommend a good build that is centered around using guns? I've heard mech guns are good? Any help will be very much appreciated. Thanks!
