The Best way to get into Gul'Dan heroic Groups.

So I was applying constantly to heroic Gul'Dan groups and I have a text copied so that I can paste it to the leader of the group so I don't need to type it all the time which is something like this "9/10 know fight well".But I didnt know the last thing I copied was a Music video from youtube and accidentally linked it to the leader instead of my normal "9/10 know fight well".This was the video - https://www.youtube.com/watch?v=koGrknEchhkAs soon as I saw the mistake I thought I had no chance of getting into that group.... oh boy was I wrong. The leader loved it so much he invited me!This was his reaction and mine - http://ift.tt/2mqtY4l his friends were digging the song - http://ift.tt/2mSkLxM if any of you are trying to get into these groups maybe all you need to do is link them some sweet tunes :D
