I was finishin up vashj'ir on an alt I just got to 85 and was swimmin around and the npcscan went off, I got excited and immediately began searching... Yeah... So.. I targeted it.. took me forever to find it.. I even did a double look at the MODEL of the rare.. and was all like "weird.. a whale shark. Now that's just weird to make an easy elite at 85 look like a whale shark." aaaaaaaand then I noticed it's HP and about wet my pants because I was milimeters away from pulling it. But I must admit the death wouldve been funny.
So I looked up what loot it dropped and it seemed that.. for having to get a raid group to down him.. it just doesnt seem like worth the time for somethin you'll replace quickly.
