Also, the game is not "improving", its just getting updates that should have been in the game since day 1.
Maybe you should grow some weuvos, have some patients, and stop complaining. People are acting like this game needed to be released in a perfect state. If you're new to the way Blizzard releases their games, then you should understand this is the way they do things. Has there ever been a game released by Blizzard in a perfect state? Nope and there never will be.
So the game wasn't released in perfect status. Improvements were made and game play experience has improved. The game has improved by a lot, and no game is released in a perfect state. Be a man and stop complaining or go play something else you enjoy.
