I think if you want drops, then playing Strikes is the wrong thing to do. Strikes are for people who want to get their Vanguard Marks quickly, and get their guaranteed gear at the end of a Strike. I already got more Legendary drops from playing casually on Patrols, doing my Bounties. I don't want to waste 30 minutes on Strikes, in hopes that some random mob will drop something decent. I'm playing it for the guaranteed reward, not the random loot drop chance.
