An updated Alterac Valley would be a better warfront than warfronts.

Think about it. In AV you can gather resources (blood, armor scraps, etc...) similar to warfronts as far as lumber and iron.Those resources in AV are used for several things. They are used to upgrade the guards at the various flag points to make them elite and much harder to kill (although the scaling is off these days). They are used to send npcs flying on bats to go bomb the enemy from the air and my favorite, summoning lok the ice lord and help him get bigger by buffing and healing him.This expansion should have been all about updating battlegrounds to the modern day in many aspects. Balance of maps(remember when they moved the horde cave to be closer?), art, their new npc ai in bgs, vendors in bgs selling cool stuff etc...Oh and its PvP!
