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.
