There isn’t such a thing as “pvp gear”. There is gear that can be used for pvp, and gear that you can get from doing pvp, but this gear isn’t any different than the gear you get from any other source.
If you’re talking about gear you get from low level pvp (like random bg’s) then the ilvl is fine. After all, doing a random bg is the pvp equivalent of doing lfr, and you aren’t getting heroic level gear from that either. If you want higher ilvl gear from pvp, do rated stuff.
