I'm someone who PvP's almost exclusively in every MMO I play.
I can't tell exactly how this system works. All I can say is that i'm lvl 21 and I top the charts in almost every match I'm in. It's nice being able to pvp with friends and guildmates regardless of lvls. It's also nice not being in some 20-29 zone where I'm gimped. I am very confused however about the stat scaling. I can't tell whether I should bother worrying about my stats or not.
