LOL you definitely have been missing out. I've gotten BY FAR more class mats from random drops than I have ever gotten from the end of the game. While you are guaranteed more at the end, the green and blue drops throughout It takes 10 mins to finish a strike when you kill everything and on average I get at least 3 green/blue drops each strike then add that onto 2-4 engrams at the end. With 3 people killing everything, you get glimmer from consumables, tons of drops from enemies including consumables, 31 faction marks, and you finish bounties all at the same time. By the time you finish your 30 mins at the exclusion zone, I've already done 3 strikes. I will have more engrams, enough glimmer for at least 3 upgrades, multiple bounties completed, and of course a bunch of stuff to break down for class mats. Instead of doing bounties one by one and going to missions and such, 1 strike can usually satisfy a ton of requirements. For example, hive/ fallen majors can easily be satisfied during the omnigul strike, vex majors in the undying mind, etc... 1 hour of strike playlist usually nets me ~30 engrams, 15k+ glimmer, all bounties done, and on top of that 186 faction rank (31*6). There are definitely some bounties that are done way faster in the hive mission but in a case such as yesterday where I had vex, hive, and fallen majors to kill + complete a strike without dying, 100 headshots, kill 100 enemies (mostly older bounties), 1 hour of strike playlist satisfied all of that. Of course I don't run strikes often since I don't need anything from strikes but on the occasion I need class mats, glimmer, and I have bounties to do? Definitely strikes all the way and I will make sure to kill everything. Speed running strikes is just such as waste when you consider you're likely missing out on at least 3 engram drops which can be the difference between having to run 1 more strike for an upgrade. In the end it's faster to just kill everything and get drops that way than just skipping everything and having to run an entire strike all the way through for 1 or 2 more mats.
