Some other options I'd like to see:
#1. Vanguard commendations become faction commendations. Why should we not be rewarded for sporting their ships, guns, armors, shaders, ect.?
#2. Faction reputation boosters. I'm still perplexed we don't or didn't have these all along.
#3. Reputation boosters for playing a certain playlist or heroic strike x amount of times per week.
Feel free to discuss other alternatives too.

It's way easier now than any other time in Destiny. Personally, I see little point in ranking up after rank 3, since you can then buy whatever they're selling. Shaders and crappy gear aren't exactly an incentive IMO
