So I see a lot of strategies for soloing the beginning of Crota's end (before I move on, this strategy best suits Titans, unless you feel like running through all the lamps), but personally I like this one the most. Using my Titan with upgraded lift, when I'm at the second lamp I jump ontop of the rock nearby then jump ontop of the wall behind the lamp. Then I head to the left, kill the knight, then proceed to the bridge (fairly easy as long as you don't kill any thralls as they will respawn). Before activating the last lamp, I step in the circle. Then bringing the weight of darkness down (doesn't have to be all the way), facing the bridge I hop between the rock and part of the bridge to the left. While atop of those, I'm unreachable by thralls and Knights while out of range of the ogre. If the ogre does come near i pop a bubble, or I bring it down with black hammer. Hope this strategy works, if you'd like I'll try to post a video of it showing how to do it. Good luck, and hope RNGesus gives you something good :) EDIT: I'll try to upload the video today, depending on the time I have it will take a bit before it goes up. In the mean time just hang tight :)
