I mostly just do normal content, and a few extremes, and I don't think normal content has gotten too hard. What's happened mostly is that a lot of the fights now assume that you know (as you should after 100 levels) to pay attention to the boss's cast bar and actually look at the boss to see for example if he's going to hit left or right. A lot of players have gotten through a lot of fights without learning to watch those things, but it's truly not too difficult for anyone.
