Yesterday we talked about what new game features you might be looking forward to. Today let's consider the flip-side -- changes we might see in the future that you hope will never happen. When you can't be sure what Blizzard might have planned for the game, it's easy to fear for the worse. More class nerfs? Hundred player raid content? More bugged, unbeatable encounters (at least until Blizzard hotfixes them)? Or perhaps something completely different -- what game change do you most dread seeing?
