Changing Leatherworking

[rpar01]

I am a tribal leatherworker, I now want to be a dragonscale leatherworker. Is this possible? I went to the expert leatherworker in darnassus and there was no untrain option. I then went to the tribal trainer in wherever she is and no option to untrain. Now im stuck. what do i do?

Not sure there is a difference anymore. After BC came out I could train in all the patterns. Of course I dropped LW for Herbalism. It was driving me crazy.
