I hate it when the game changes a Class. Especially if it has been a change that has effected something for years. Mess with a character or mess with UI = people quitting. ~like can't believe I'm saying that (I like a Duder post )
I agree that big changes can lead to people giving up and leaving. However, I think the informed folks are all in agreeance that the necro updates were t benefit the class. Regardless, it changes the way raiders and non-raiders have played for years. Which to some is a destruction of their class/character (Even if the changes are to their benefit). So it's understandable why some folks are upset and fed up. But the game changes, always has, and so must our play. I know I wouldn't be playing if the game and the classes I play didn't change over the years, way too boring.
