Halaa is a neutral city in Nagrand that was designed by Blizzard to be an outdoor PvP hotspot. Fighting here grants you tokens you can use to buy PvP stuff (read: with resilience) and controling the city grants a faction a zone-wide damage buff. While Halaa may have been successful some time ago, when dozens of levelling players where swarming Nagrand, it is very hard today to have a fight there involving more than 5 to 10 players.
Halaa is actually fun to play, but most players have no interest in coming here and this ruins the concept. While you would expect fights in Halaa several times a day, it hardly happens one time a week on a very well populated server. Is Halaa definitely broken ? Can Blizzard do something ? Hell yes, and you'll find out how in the rest of this article.
