Here's something for you. If someone thinks the game has a high enough quality to spend their own money on, and spend time playing, who the hell are you to tell them that they are wrong?
You opinion on a games quality is null and void when compared to someone who is still getting enjoyment out of it.
If they game stops being enjoyable for me, I'll stop playing. I also wont go on a forum dedicated for those who do enjoy the game, to try and convert them away from something they enjoy.
Why do people like you, have a problem with people still enjoying WoW? I'm seriously confused by this.
I don't care about subscription numbers. They mean nothing to me as long as it doesn't directly effect my personal enjoyment inside the world of warcraft. Nothing people like you can say will change that fact.
