His name tag will actually have the ^^ in it... for example, it would say
A mob^^ I can't remember for sure but this feature might only show up if you have your con system switched back to the old version... I think that the whole heroic mob system was "scrapped" in favor of the new "simple" conning system.
You can switch things back and forth in options page...

- You can switch between the old system and the new one by selecting the User Interface tab on the Options window. Under the Name and Chat Bubble heading, you can toggle the NPC Evaluation drop-down between Simple (new system) and Detailed (old system).
