Some nice unexpected changes (or slightly unexpected)
Viewable goggles is a step in the right direction. I like it even though we had a hint with the screenie.
Assigning metas to spells is long long overdue. Glad they got too it, hope they got it right, or get it right shortly after release

Buffing the raid bosses is good. Im very happy about that. Especially if the n-e scales well.
Im interested to see how the ui changes to health bars implements. Ive always thought it was way to simple the way it was. Hopefully this is a step in the direction of more customization such as volume sliders

Lowering Ki costs on higher end ki strikes is also a step in the right direction after the autocrit nerf. Hopefully they continue to tweak it. Although I havent played my monk in a while, I plan to start playing him tonight again.
Increased xp is good. Especially after all the xp nerfs the past few years.
More crafting tweaking is good as well, though its just a slight tweak this time it seams. Taking +3 tomes out of the boxes makes me happy
