Cheers everyone,
I'm a bit confused and I can't find any thread/guide/blue post about this matter...

Do enchants and sockets work in rated PvP now?

Also, I've heard that stats and abilities in general are slightly tuned for the PvP scenarios. How much does that impact the game? Is, let's say, a 10ilvl gap noticeable as much as it is in a raid/m+ environment?
