If you notice the quest marker in "The Conversation" is pointing backwards once you're at Enkaar, or the darkness zone doesn't work, or the enemies stop dropping healing orbs, just go to orbit. I didn't notice that, and wasted an hour of my time. I was so salty about this.
I started "The Conversation" to finish up the quest for "The Last Word", which I'd been having fun working on at my own pace. Once the pvp portion was finished, I relaxed. How hard could the pve portion be? HA. I REALLY struggled with Enkaar. I tried adjusting my sensitivity many times, and after an hour of frustration, I finally defeated him. I shouted in triumph! And then... it glitched. The weapon never popped. I tried running all around the area, but nothing made the weapon appear, so to orbit I went.
