With this mixer out, what do you guys think microsoft will integrate for streaming?

Mixer and Facebook Messenger cannot be integrated. Mixer is a platform for streaming, not private conversation with a friend or a group of friends. So what exactly you want to do - stream for your friend or have a private call with your friend?

twitch was on xbox from the beginning and was the only way to stream, mixer came out a few years later, as mixer was not doing well they sold the assets to facebook and closed mixer

any ads in the twitch stream are there by twitch not microsoft, dont want ads then sign up to prime i think as amazon own twitch.

you get ads with youtube also.

I rarely use streaming, but when i do it i prefer to use mixer because the integration with xbox and win10

A sort of Mixer integration might allow that, however it would be easier if each of you streamed your session via mixer and the other could watch on a mobile, pc etc.

Unfortunately, with Mixer going away, there is no easy and direct "2-step" streaming integration anymore.

Until they come up with a better replacement for the removed Mixer, you have to live with the cumbersome Twitch process, I'm afraid.
