Yup, streaming is prioritised to ensure a smooth experience. Makes me happy to get some positive feedback for a change, although I do understand when people are upset about the international issue.
Regarding international, on my side I see Google services takes a long time to load, especially hangouts. You get a hand full of sites that also takes a while to load, but oddly enough any streaming service I have tried, even the really crappy one's work without a buffer in sight.
