So, I figured out a way to easily solo the lamps hard mode as a 31 titan.
Jump up like normal, kill the knight etc.
When you get to the end, trigger it. When the ogre moves past the last large rock (basically when he almost gets in shooting range), ADS with patience and time to invis. This lasts for like 8-10 seconds. When that drops, pop your bubble with extended time. At that point I swapped to mida multi-tool for runspeed. My shield dropped and I started running, as I did the bridge formed and the weight fell off. Jumped to avoid the ogres initial salvo and run like a mofo. Nailed it on the first attempt.
