I encountered a Lost Son of Arugal the other day

I was leveling a Druid in Silverpine when it suddenly appeared, and, tbh, I felt kinda bad for it. Arugal dead, his Worgen dead as well, the only remaining Worgen were in the Alliance, he was wondering the forest alone. FeelsBadManHe also had what appears to be an outdated Worgen model. So not only was he alone, he was ugly too. FeelsBadManV2I put him out of his misery. No such creature should be left like that. However, he was the only rare mob that challenged me and actually killed me when I wasn't focused (I was turning the camera to take a screenshot and forgot to heal, I ran him down afterwards).Was old Silverpine full of these guys, only they were Elite (even worse)?
