Oh, GOD yes. As many know I've been here since the beginning like many of you fine folks. I've played WoW since 2005. Sadly, I'm not subbed anymore. Haven't been for a while.
The thing that seriously killed it for me was the fact that they 100% destroyed the game world I grew up in and loved so much. That was the single most detrimental thing they could have done that just annihilated any nostalgia I had, because well, it's just gone. It's literally all changed.
Biggest mistake IMO, in their development cycle in the last 11 years.
