There are good and bad ways of making the game "easier". The journal is a good way.
Blizzard has realized that instead of making content easy for everyone to manage, they must instead focus more on teaching people how to play. The fact that leveling teaches you almost nothing is really Blizzards own fault, but at least they're trying to make up for it.
It's not like it's giving us information we previously didn't have. It's like saying the boss emotes in the middle of the screen make fights easier, despite everyone having used bossmods in the past years.
