There was a really cool change in the 2.4 Patch that totally went over my head until about last week. Since it is becoming harder and harder for newly minted level 70 to compete with people who went through three seasons of Arena, something had to be done.

Blizzard made some basic PVP gear set available for purchase from the Outland faction vendors. So, all that grinding for Thrallmar or Cenarion Expedition you have done can now pay off. You have to be honored with the faction, which is the same reputation you need to buy a heroic key. The cost of each piece is also quite minor, on average 10 gold for each piece. At level 70 that's a few daily quests that can be done in 20 mins. There is a set for every class.
