I've never completed one. I have jumped in solo to a couple just to bang my head against the wall though. My favorite activity right now is the 380 story rotation. Aside from that,strikes. I liked the Forge for a while. Like COO for a while. Can't stand either one now. I don't even know if I'll bother with the COO part of the book. Last April I played the crap out of POE. Now I can't stand it...all last gen console players in there last I looked,and nobody plays the objective.
