To be fair, the rules here are a little more complicated than most first-person shooters (since you can do a lot more than just shoot at each other), so obviously the maps would presumably be a little more complicated as well. But in the age when players have access to the Neverwinter Nights toolset and even the Forge on Halo 3, surely it's a little crazy that Blizzard takes months to release one map, when other great games can pump out whole packs of them in the same time.
Now, this is WoW Insider, so it's ok if you're a Blizzard apologist. It's fine for you to say "Blizzard has the biggest game in the world not despite the fact that they're so slow, but because of it," and it's fine for you to be a fanboy/girl and say you'd rather wait three years for a Blizzard-quality Arathi Basin than play a whole "Hidden Fronts" pack. And the truth is that when Blizzard does release content, they don't disappoint. But we're still left wondering just why, after doing this for so long and having so much practice at it, it still takes them so long to do it.
