Well, when running on vanguard tiger playlist, my ultimate goal is the end-of-strike rewards. Granted you can play the RNG and snag drops from the mobs along the way, but there are sections of each strike i will drive straight through in the interest of faster completion. Although i will stop and look at what the other two guardians in my striketeam are doing. If theyre both wading through all the mobs and im the only one flying throug, then ill stop and rejoin. If at least one of the other guys wants to cruise through also, then ill keep going. With as much damage as bosses can soak up and as long as some of the strikes can take, killing every mob along the way can be time consuming. Mars comes to mind as one of the longer ones in which i usually try to run pass many areas.
