To rolfards point, if you want the best compromise to picking and hunting then either ranged or UAC will likely be your best bet. I love UAC, I have a 47 train UAC wizard that is a blast, having said that I have an idea in my head of a rogue being from Assassins Creed, which means a blade. The first thing I would say is, figure out what you want your rogue to be, in your head, how do you see it, then train for that. I got 3 rogues to mid 20's in GS3 before I settled on my current one, it is a lot easier to fix mistakes now or change your mind.
I have never played with ranged, but it seems pretty potent.
