Weekly Nexus

So i'm soloing the Nexus. 26 warlock. not the best gear, but i'm making it. Get all the way down to the Nexus. just taking my time. only solar weapon i have is my sniper rifle. got plenty of ammo packs. kill a couple mino's jump down...and to the left of the entrance tunnel i find a little cubby hole. sweet i'll go in here..mobs can only come at me from one direction..and i've got a clean line to the boss. so the fight ensues. drop a couple adds...duck back into my cubby...take a couple shots at the boss...duck back into my cubby. get the boss down to a sliver of health..and i get hit by a Hobgoblin death ray. ooooh soo close. well here's to trying again tomorrow. *Just a little note to those in the 25-27 range. Even if you don't think if you can finish the weekly by yourself..try it. Every time you kill a mob its a chance to drop something good. I managed to get a couple blue engrams out of this run and i didn't finish the mission.
