There is no dragon strikes. Dragon strikes (the 28+) version that gave you pretty good rewards has been removed. That was a BIG source of worthy end game content. You can't even buy legendary gear to improve your light level without TTK dude, it's straight non sense. Why penalize people for not buying the same thing twice? Borderlands 2 Tiny Tina DLC was AMAZING and if you didn't want it, they didn't take away content you already own and basically FORCED you to buy it. Destiny is literally holding End Game content hostage for TTK. Come on dude
