I had never used mGear for facial rigging before but after seeing that quick demo on Linkedin today, I decided to give it a go.
Ryan Griffing, the author of the article. mentions there are issue with mGear with the Pymel change so he injects some bits of code in the process.
I decided to finally give it a go and see what this is all about and man! It is fantastic! 
and in mGear 5.2.1 I didn’t even need to make the change like Ryan did.
Now I am wondering though. Why is [legacy] mentionned in the menu, is there a new version of the Facial Rigger I just can’t find?
