First off, this is not a "When should i start?" or a "What should i put my points into?" Topic.

My question is this : How much XP do you need to Ping? I heard it was the same as Being LVL50, I also heard it was 1/3 of a Regular LVL. Which of these (if any) is true?

I was also wondering : If you are LVL65 does a AA take longer to acheive than if you were LVL51?
