Different patch, different focus. 
Per the patch notes, our main focus was to add a variety of different, new powers for everyone to have a chance to play with them. We also wanted to focus on a new, unique, and different type of Seasonal buff. That’s why there are very few instances of class-specific changes and no quality of life changes.
Quality of life was the focus for 2.6.5, and maybe we’ll revisit other areas of improvement for a future patch. It’s just not in the cards for 2.6.6.
