I suspect it has to do with content difficulty being made easier. This inevitable causes mid and hardcore players to blend into the casual, inexperienced or downright bad crowd. Unfortunately, these two subgroups of players do not always mesh well together, especially when it's bad players. Zurvan stands as a prime example. His mechanics are too easy to skip, thus the "must skip Soar" meme was born. It isn't difficult to do mind you but plenty of raiders aim for efficiency whereas more casual minded ones aim to just have fun. Once again, that doesn't always blend well.
