I think it would be especially useful in this game given it's pace of content (this is not a bash). For example, take all those people who got r50 pretty fast and completed the storyline missions within say... 2-3 months of game release. Do you really think those people are going to remember wtf happened when they continue adding missions to the storyline a year or more later? I'd be clueless! Would have to YouTube all the missions just to understand what's going on (and it's never the same).
