Aura build help

I just recently came back to the game not long ago after a long break and I was looking for an Aura build for my scion. I was wanting to group with friends with full auras but I can't seem to find one anymore. Are they not viable or can they just not be done anymore?

Most (aura) support builds start as templar (guardian) or witch (necromant) because of the ascendancies. If you look at some of the support builds in the witch builds list you'll see that the trees can easily be modified to start as scion. Scion ascendancies would be necromant + guardian i guess.
