@Furmetal: Nope doesnt work /cast pack hobgoblin.
@Deielrion: Yea worgen have trainer for they racials but now they all learn them on instant when players make a worgen on fun realm. For goblin trainer there is any one in the game as far i know.
-I think problem is that you need to do quest at the end of goblin start zone http://www.db.pandawow.me?quest=25267 and on fun you skip that all so i think it would be best if we get instant learn this skill if possible.
