So, basically instead of playing the game as you designed, the only real effective way to increase light is to grind the same Septiks Perfected strike over and over? Why is this the case? Is it that hard to have higher light rares drop on the all missions you do? Every strike? Once in a while in Crucible? Bad design Bungie... we should play a variety and still be able to achieve the same as grinding one stupid strike over and over.
