How do you Rank up quick?

[Cero0]

I see lots of people with the gear, but I have no idea how they rank up so fast. I want to get the gear for appearance and I have several pieces already however only level 25ish. How do people rank up "fast"?

Someone in my server asked me how to rank up fast when Seal rock came out(he was like rank 15 or something), My answer was easy: Do pvp roulette everyday,Challenge log and Q non stop for everypvp, hes currently rank 45.
