There are a few snags to implementing these, and foremost among them is how many players computers can actually handle it about wow gold. Better graphics means your computer has to work harder, and big, sudden graphics upgrades in other games had the ugly result of making them virtually unplayable for a lot of people. Blizzard wants to avoid this, obviously.
When Blizzard collects "non-personal system specifications," what I think that means (at least partially) is that they try to get a sense of how many players would be completely screwed out of playing the game, period, if they implemented certain graphical improvements. Hardcore gamers might scoff about wow gold, but one of the contributing factors to WoW enduring popularity is that it does not require you to run an insanely expensive or complicated system to enjoy the game. Everyone wants to see better graphics. Nobody wants to deal with the technical issues that might result.
It is getting really old getting disconnected 3 or 4 times trying to log into Dalaran. I never have trouble logging in anywhere else about wow gold, just "Lagaran." Is Blizzard ever gonna fix this lag problem?
The trouble with Dalaran is that it has a lot of players, a lot of NPCs, and a lot of movement, all of which is set across the backdrop of a city that has to be rendered in 3D due to flying mounts. Even playing with the sort of settings that turn Azeroth into a Third World country -- actually, that is an insult to Third World countries about wow gold, and I apologize. Even playing with the sort of settings that turn Azeroth into New Jersey, your computer still has to render an awful lot of stuff, and that is made worse by the absence of visual shortcuts and cheats you will find in cities like Orgrimmar and Stormwind, where the developers only had to put in what you could see from the ground.
