I am sure this is a pretty basic question, but I am a complete newb when it comes to the World Boss (only participated in it once). My question is, if I do a WB, will it give me credit for all the ones I missed in the past? As I said, I only did it once on one of my characters, so I am pretty far behind. Is it too late for me to get my Legendary Cloak? Or am I good?
