Since there seem to be a lot of "I hate Blizzard they killed WoW" posts around at the moment (and granted the patch isn't working as smoothly as we had all hoped) I figured I would counter it a little by listing the things that I love about our favorite game designers.
1. They created World of Warcraft
Lets face it, they did sort of make this game we're all so eager to play without bugs.
1a. By extension they gave us something to blog about
2. Blizzard communicates with their players
Everybody wants the blue posts, the blue posts give information. And no matter what we throw at their heads they keep coming back and embrace their players again.
GC you're the best. You share what you can share, and stay calm no matter what people say about you.
4. Blizzard listens to their players
They don't ask us to test stuff for nothing. If we come up with mistakes they will take a look at them and see if they can reproduce them. If their findings are the same as ours they will change it.
5. Special Touches
Surely we all remember Ezra "Ephoenix" Chatterton, right? Blizzard does good when they can do good. And Ephoenix has not been the only one, there are many cases of where they paid some special attention to those in need.
If you've never been to this site you should definitely try it out. GMs generally have a pretty good sense of humor, and if you don't believe me, as the next GM that treats your ticket to sing a song for you ;)
Not all games allow you to just flip a few addons in and change the way you play the game. Blizzard does, and I'm sure most of us are pretty thankful for that.
All in all, I think with the mess going on with the current patch most Blizzard employees are working their asses off to get the game back into working order. Not only because it is their job, but because they care about this game as much as we all do.
