One of the things that stands out as the strangest item I have seen in a patch is the addition of arena points to battlegrounds. Huh? Aren't arena points by definition supposted to come from Arenas?

• PvP
  • Battlegrounds
    • Battleground Experience: Battleground experience gained is now based on the level of the player gaining experience, rather than the highest possible player level in that Battleground.
    • All level 71-80 Battleground daily quests will now award 25 Arena points in addition to their current rewards.
