As the title says and I'm still trying to figure out why you'd take such an interesting aspect out the game. Those exclusives were one the main reasons I grinded strikes for exclusives like the Dark blade helm, grasp of malok, Mongrel grasps, psi on flayer mantles, imago loop, hood of malok, mau'uals maulers, or even the infamous Hopscotch Pilgrim. Right now there's no reason to run strikes at all unless you want nameless midnight which you get from the story and Orgin story which anyone can do without because Uriel's gift is just as good if not better. Just bring them back and give us a reason to run them.
