Guide: Factions, Rep, and Marks

I found this guide to be particularly helpful when it came time to set my sights on a new goal once I hit level 20. I hope you guys do too! Also, if you haven't check it out, the [url=http://www.reddit.com/r/DestinyTheGame/comments/2g37d9/guide_vanguard_rep_faction_rep_and_vanguard_marks/]Destiny subreddit[/url] is filled with lots of great discussion about some of the more intricate parts of the game. I'll link stuff I find on there that's particularly cool or helpful. Teaks out!
