There's no skill requirement. It's just guilds account sharing to get the amount of time required to hit Rank 13-14 on a single character and then rotating in another character.
I only got up to First Sergeant in Classic before burning out and giving up. I know a lot of people used to PVP like it was a fulltime job and still only managed to hit like Rank 10.
If that's your idea of fun, I guess go for it. I've got a life.
