Realizing their usefulness and implementing them has seemed to go in different directions.
Elementalists seem to be well suited for them in the way I use my eles. Armor usually has Minor Energy Storage,Major/Superior Vigor and the headpiece of choice sports the sup rune of the element or Superior energy storage.
Monks,on the other hand, are the exact opposite,since most monks use all their attributes in a build of choice. Div Fav,Healing and Protection, at the least.
Warriors have similar problems, since Strength,Tactics,Vigor, and Absorbtion are all in use by nearly any warrior worth his/her salt.
I am looking more into how others have used these new runes of attunement to their benefit. Ideas and usage are always welcome.
