It’s less than you think because no one in their right mind would sign up for a PvP server and expect it to be PvE for them the whole way.
The alliance that complain are on horde dominated servers in which there are ALWAYS more horde out camping 24/7. The game is literally unplayable. They can’t even get to dungeons to level. I’m glad you enjoy the challenge of being horde on a very alliance dominated server. But there’s a difference between wPvP and the game being unplayable.
