The way I see it... Rush the lvl 24 strikes kill boss get legendary gear... Only kill adds for ammo. If you spend a hour fighting level 15s I will leave you in the dust. More vanguard marks, better gear, and less time spent killing every drake hiding around every corner. I got 2 legendary and 1 exotic from 4 strikes this week...I finished the VoG before you finish killing adds there's a problem. If you want to mine goto cosmodrome for 6 hours...rush and win. Cry because you can't rush.
