I realize this post may be old. Not sure. But I used to struggle to level my vanguard and, when I saw the introduction of vanguard commendations, I was angry. Once I started doing the nightfallIs and weekly heroics every reset Tuesday, my vanguard reputation was going up around twice a week. I make it a point to do all of the vanguard bounties daily if I can. That's 500-600 a day plus the patrol points. It seems like I level my vanguard every week when I complete the nightfall. I now have around 25 vanguard commendations in my vault and nothing to use them for. I started a 3rd character a couple of weeks ago and got him to level 31 in a week. I've already run Crota's End with him twice. I actually was able to do it my first week. He's now rank 5 or do with vanguard. The only problem with leveling that fast is you don't spend hours and hours picking up armor and weapons to break down. So I have run into the problem of not having enough hadronic essence (warlock) for his armor upgrading. With my first character (Titan) I played a few hundred hours and never had s shortage of plasteeel plating. But I'm breaking myself buying low level armor just to break down for the hadronic essence. That's been my toughest problem. Even though I give every armor engram earned by my other characters to him it's still not enough. I wish there was a way to buy those materials. It takes 25 for each armor upgrade slot until you reach the last row where shards are required. And breaking down a piece of armor only gives you 1 or 2 material each time.
