Ticket response
Thanks for contacting us regarding
I wanted to discuss this matter with you in-game but unfortunately you weren't online by the time I received your ticket.
Unfortunately we can't give you a certain answer on whether or not the new traits will work in PvP as this is a question more for the developers than Customer Support.
All we have from the patch notes is: "In instanced PvP (arenas, battlegrounds, and Ashran), Artifacts now grant a minimum Stamina increase to all players. This minimum is equivalent to the purchase of 36 points, one of which is the trait which grants 10% Stamina."
I recommend either asking on the PvP forums as a player may have already found that out or tweet our devs at:

I have also noticed that your account does not have a Battle.net Authenticator! This is a very good way to ensure the security of your account from those who would attempt to steal it.
If interested, you can find more information on the authenticator here:

Have a great weekend!
