You guys spent the entire comment section either complaining about dailies or broccoli, for some reason, so today's Queue is short. You only have yourselves to blame! And this guy is gonna beat you up for it. You messed with the wrong Queue writer.
I'm currently levelling a lower level Monk in the Old World and seeing a lot of the changes Blizzard did with the Cataclysm. But while the quests and content feel fresh the overall aesthetic of the game hasn't and while WoW was obviously designed to age well, it feels to me that the zone textures and doodads conceived of over ten years ago look really...really bad when compared to similar stuff in Pandaria and Cata zones. Trees and Bushes in places like Darkshore or Winterspring, or some of the older monster models now look positively dreadful (the Frog is a particularly horrific example in my opinion).
While I doubt Blizzard will ever upgrade the basic game engine, do you think they'll ever give their older monsters and older zones a fresh lick of paint?
Take this one to the bank: after the mess that the amount of attention the dev team focused on Cataclysm's 1-60 revamp caused on the expansion's development, we won't be seeing any sweeping changes to the old world for a very long time. Don't misunderstand me: the revamp was completely necessary. But it's all we're getting.
