It's a fairly easy, yet repetitive, process once you get the strike playlists. I capped out on the second day and it looks like I'm going to cap out the weekly rep too soon. Assuming there is a weekly cap, not that many things are explained in this game but I see an almost full circle similar to the one for marks so I assume it's the same deal. The menues could really need an overhaul, with a proper stat page. The only way of tracking progress is afaik to either go to the strike screen, for marks, or to the vendor, for rep.
