Well some people think that you will have access to different PvP battlezones in different cities. There is one Capitals city and 4 minor once for each race and total of 80 different battlegrounds. I doubt you will be able to access all battelgrounds in the place you started. And as they say, the more lvl you get to the more places you gain the access, similar with train. First you can only travel to one station the higher lvl you gain the longer you can travel in the train until one lvl you can buy yourself a car and ride it.
So since you ca't access many places from the start, that means that PvP zones can't be accessed with your lvl which does serve as lvl limit in a certain way to me, but that's just how i think.

I had another idea of how you can do it, there are games such as America's Army or Gunz in which you need specific lvl to access certain servers. In Gunz it's mostly because you can purchase better cloth which makes you hard to kill and better weapons which makes it easy for you to kill others so there are different lvl stages to cut the unfairness. But in AA, there you have different lvl of rank, you start out with 10, you can reach 1 if you want by TKing all the way by why advance backwards? Anyhow i n that game each server can have the honor lvl requirements at different stages, such as only player after honor lvl 40 can enter this server, or no player above honor 20 can enter this servers (for noobs). Anyhow you get the idea, they could do similar to that idea so you can skip battlezones with noobs that dont know what word teamwork means, which they understand when they gain lvl unless they are totaly stupid.
