In the past three expansion, TBC, wotlk, and Cata. I've always prefer the World PvP in TBC for many reasons, Nagrand for the flying bombing quest, collecting tokens and getting the mounts from fighting Alliance or Horde. Then HP with it towers, and Terokkar with it towers then obtaining the Token in the nearby dungeons. There has always seem to be a lot gained from TBC pvp. So what your favourite world pvp and reason why?
