Every bounty has a story mission where you can complete it quickly and with little time involved. Strikes are a horrible way to collect bounties because you have no control over the area your playing. You could easily do 3+ strikes before you get one that will allow you to complete bounties. Killing Hive majors or ultras cannot be don't on Venus or Mars strikes so why waste your time playing them if you can go directly to the area with those enemies. The Bounties that require precision damage or killing enemies without taking damage can be done doing the story bounties to save time. The exclusion zone is easily the fastest way to collect glimmer because you can aquire 10,000 in under 25 minutes. People complain they never get the drops they want, but waste time not doing things that will allow those drops to happen. It blows my mind.
