Usually the mentors I've come across in duty finder are rude and impatient. I had 1 tank a while ago in the vault with a mentor status and no right side tanking accessories. As a matter of fact they were all less than ilvl 50 if i remember correctly and didn't know how to tank and hold aggro for the life of him. I wish there was a way to report these 'special snowflakes' that just want the crown just to have it.
