I think it is possible to get to lv50 even if you max all your weapons, and do all the quests that come with it in the release September 4th. You could just do the Blackmack task a ton of times to get to lv50, or, find treasures. I don't pay attention if I get rep when I get treasures, so I am not sure if you get rep for them. I have been told you do get rep for finding treasures. If you do one of these things, it would probably take months.... maybe years depending how much you play and how much you play cards.
