Well if you want pvp gear, look at the expertise statistic, its the ''pvp'' stat.
The only thing you need imo in the level 10-49 is pve gear up to date, you dont really need pvp gear in this braket. However, if you have trouble to perform in a wz, you should get some 40+ pvp gear (gear with expertise) and put the enhancement with expertise in every single piece of orange armor you have.
