Hello Firekeeper, and Philanty,
As for distance attunements, I personally have not experienced them, but I have spoken with some that have. They, for the most part, seem to have felt it and experienced it just as much as if they where there in person. These attunements where done via another message board I am on, and all the feedback there on that was quite positive, and the attunements many.
All the best,
Dina
