Yesterday in our guide for Eternal Farming, it was made very clear that Wintergrasp is hands down the best spot for farming Crystallized Whatevers if you don't have Mining or Herbalism. That's not the only thing that's easily farmed there, either. It's packed full of herbs and ore. It's currently the only place in all of Northrend that you can find Frost Lotus nodes. Not just Frost Lotus dropping off of Icethorn or whatever, but actual Frost Lotus nodes.
Now, I'm a PvE kiddie at heart. I'll PvP from time to time, but it's not exactly my favorite thing ever. I usually avoid it. Wintergrasp has totally sucked me in, though. The draw of riches has pulled me into the zone, and when the PvP starts it's legitimately fun. I originally thought it was silly that the best farming spot for everything was a PvP zone, but I've warmed up to it. I'm on a PvE server, but the element of risk and reward has become kind of exhilarating. I still have no interest on playing on a PvP server, however.
